Finally: The end of the road for Flash!

Wow. I go off-line for a week on vacation and Adobe drops the bombshell that it’s abandoning mobile and set-top Flash in order facilitate the move to HTML 5. This is such monumental and welcome news that I had to pause my time away from the computer to comment. First, as usual, John Gruber of Daring Fireball has been covering this topic very well. It’s starting to be old news already but if you’re interested, you should check out some of what he’s linked to.

Overall, I’ve never really liked Macromedia and the Adobe Flash. Annoying video ads aside (as these can be done in HTML5 as well) Flash, while a cool technology, has always been a pain if you were interested in fiddling with funny, often Open Source, and under-developed operating systems on obscure CPU architectures. It happens that I’m in to this, so I’ve never really bought in to Flash and have been a vocal opponent of it for many years. Moreover, Flash is terrible from an accessibility perspective, as most screen readers can’t deal with it. Flash is why good web standards are so important. At it’s peak, it was installed on something like 98% of browsers. As a web developer interested in standards compliance, I’ve often had to explain to potential customers why Flash is a problem. Unfortunately, lack of screen reader support and poor accessibility in general are a harder sell than mentioning that it won’t work on iPhones and iPads.

All of this to say that I’m glad to hear that Adobe, who makes fantastic tools for creative people, is going to phase out Flash in favour of HTML5. Open technologies owned by no one, enhancing the web for everyone. Adobe has compelling tools for print and on-line media already. They recently acquired the companies behind TypeKit and PhoneGap. I can’t wait to use Adobe’s new Creative Suite that integrates these great technologies.

However, all of this great news isn’t what prompted this blog post. Rather, it was the following Economist article entitled “Flash Fried”. It is a mostly balanced, well-written article that goes off the rails in the last two sentences:

Widespread adoption of the new standard is likely to make it impossible for any one company to hold sway over online interaction. It may be too soon for Apple to gloat.

The first sentence is why the death of mobile Flash should be hastened and celebrated. The second sentence is rubbish. Apple wouldn’t gloat, though it did far more to see to the first sentence come to be true than any other company. The second sentence implies that Apple wants to be the one company to hold sway over online interaction. There is absolutely no evidence that would lead any rational, informed, person to jump to this conclusion. If anything, the supposedly “open” Android platform, very firmly controlled by one company, Google, is more likely to try to position itself to hold sway over online interactions. Even if this came to pass, it would be a better situation than what lead Microsoft to a 95% lock of the desktop market share, which then lead to stagnation of innovation on-line while the dominant browser (IE6) failed to progress for years.

In light of the realities of today, Flash is a dated and flawed technology whose time has thankfully coming to an end. It was an important intermediate step between pre-Flash-driven sites and what HTML 5 will bring. We could not have jumped straight from HTML 4 to HTML 5 without something like Flash to help show the way. For this, we should all be thankful for Macromedia, and now Adobe’s, contributions. However, Flash technology is fundamentally flawed: It is controlled by one company, it has, until Apple put it’s foot down, held too much say over online interaction, and now the security and performance problems of Flash, coupled with browser advances, have deemed it largely irrelevant. We don’t miss DOS, we don’t miss punch cards, we won’t miss Flash. Technology marches on.

HP Palm Pre 3 Review: The phone that never was

It appears as though my time with Palm is drawing to a close. HP has killed off the Pre 3, the Veer, the TouchPad, and has laid off the employees responsible for the hardware. They keep making vague promises with webOS the software, but things certainly don’t look good for webOS, my favourite mobile platform, or for what was Palm. The company that popularized PDAs, pioneered smartphones, and then briefly had a run with the only compelling iOS alternative I’ve seen seems to have run out of steam. Nothing stays the same. If there was no change, there would be no hope of progress. Still, as someone who has followed Palm since it was part of 3Com and US Robotics, I will miss their innovation and attention to the user experience. (UX)

All of this said, I was unable to cut my losses with the HP TouchPad. When unreleased AT&T HP Pre 3’s started showing up on eBay, I had to bite. I ended up buying a 16GB version for $241 plus $30 shipping. At less than $300, I am very pleased that I made the purchase. webOS may be a dying platform, and the Pre 3 may be a dead-end device, but it’s a hell of a dead-end device.

The HP Palm Pre 3: End of the line for Palm

The Palm Pre 3 is the pinnacle of the form-factor that Palm developed with the original Pre. It features a 3.5″ 800×480 display, a 1.4GHz CPU, a slide-out keyboard with larger keys than the Pre 2 or Pre, 512MB of RAM, and webOS 2.2.3.

If you hated the original Pre, you won’t like the Pre 3. However, if you like a reasonably sized smartphone with a hardware keyboard and you don’t need a huge number of esoteric apps, the Pre 3 may still be a good bet.

The device is fast, fast, fast. It’s still not quite up to iPhone 4S speeds, but it’s certainly faster and more consistently so than any Android device I’ve used. As always, webOS is a lovely, elegant experience. Thankfully, 2.2.3 seems to have solved the niggling Google Sync problems I’d experienced with the Pre 2. The OS isn’t significantly different from the current release of the Pre 2’s webOS 2.1. I have been happy with the app selection in webOS for some time now. The App Catalog offers a surprisingly good selection of games and productivity apps. True, it’s nowhere close to what Android or iOS offers, but other than a lack of Netflix for the TouchPad, I haven’t really found myself missing anything from webOS. The browser has always been great. In my opinion, it is equal to iOS’ offering and far better than any Android browser. Moreover, I still think that webOS has the best mobile mail, calendar, and contacts experience of any platform. The calendar on the Pre devices in particular is so much more fluid and intuitive than anything else since Palm’s original PalmOS calendar. The attention to these details, the great multi-tasking, and the easy developer mode are why I stick to webOS even now.

The software experience is great, and so is the hardware. Closed, the Pre 3 is about the same size and width as my iPhone 3GS. It’s quite thin, considering the slide-out keyboard. The display is just fantastic. It has Gorilla Glass, so is quite tough, and the pixel density rivals the iPhone 4’s Retina Display. The screen is now the perfect size, and extra size allows the keyboard to be slightly larger, making text input that much nicer. I still prefer the horizontal keyboard of the Sony Ericsson Xperia Mini Pro or the BlackBerry Torch, but the Pre 3 is close behind, and webOS puts it over the edge for me.

The Pre 3 retains the rear-facing mirror when the keyboard is open. I know that some people complain of the vanity of this, but why not? It’s useless space otherwise. Why not make it a mirror. To me, it’s little touches like the mirror and how the device feels in the hand that make the Pre 3 hardware feel so compelling. I like my little Sony Mini Pro, but it is boxy and awkward. I like the shape of the iPhone 3GS but find the 4 and 4S to be too angular. The Pre 3 “river stone” feel is natural.

If you’ve used a Palm Pre or webOS and like what you find, the Pre 3 is a great device. If you’re happy with an iPhone, stick with an iPhone. If you like Android, good for you. BlackBerry fan? Great! Me, I like webOS. With the Pre 3, the hardware has finally caught up with the elegant software. Yes, there are things that I would change (like adding an FM radio and Dropbox integration) but on balance, this is the best smartphone for me. I don’t imagine that I’ll be using it in two years, but I’d bet money that I’ll be missing aspects of it at that time.

Good bye Palm, it’s been a good run. I’ll stick with the Pre 3 and TouchPad for now. I wish all of the great designers and engineers behind webOS the best of luck in the future. I hope they continue to influence BlackBerry, Android, and iOS development in the future.

My view of the mobile landscape – 2011.07

I’m a systems guy at Queen’s University’s School of Computing, and a budding entrepreneur with a small web development business with an eye on mobile development.  (What better way to keep my skill set current?  Then there’s the fact that my partner in both life and business happens to be the best programmer I know.)

Given that we are clearly in a shift away from desktop computing to truly personal mobile computing, I’ve been soaking it all up and taking everything in.  As such, I have a device from each of the major platforms.  Here are the devices:

  • Android: Motorola Cliq 2 (2.2), Asus Eee Pad Transformer (3.1), Archos Internet Tablet 70 (2.2)
  • iOS: iPhone 3GS, iPad 1
  • BlackBerry: Torch 9800 (BB6), PlayBook (Tablet OS 1.0.6)
  • WebOS: Palm Pre 2 (WebOS 2.1), HP TouchPad (WebOS 3.0)

I have strong opinions on what I like and don’t like, but have no particular interest in any of these platforms.  I don’t own shares, though I own and have owned many HP and Apple products over the years.  My first cell phone was a BlackBerry Curve 8320 with Bell.  I never really warmed up to it and had a rather pessimistic view of RIM until the PlayBook.  The PlayBook lead me to picking up the Torch, which I use about as often as my beloved but frustrating Palm Pre 2.  Of the above, these are my two preferred devices and platforms.  I consider myself to be a strong supporter of Open Source software, yet despite this, I have a general disdain for Android.  I find it inexcusably rough, overly complex, buggy, and garish.

I understand Apple’s success and generally recommend an iPad for most users and iPhones when someone asks me to recommend a smartphone that they won’t mind being stuck with for three years.  However, I don’t really like use iOS and am a bit worried about Apple’s clout in the market.  With that out of the way, here is my detailed take on the view of the mobile  world.

Day-to-day use (Smartphones)

Day-to-day, I find webOS the nicest to use.  However, the Pre2 reboots randomly, and I get fairly constant Google authentication errors.  At the moment, with respect to smartphones, I split my time fairly evenly between the Pre2 and my BlackBerry Torch.  The Torch isn’t as slick to use but the hardware is much better, the battery life is fantastic, and my core day-to-day requirements are met better by the Torch than by any other smartphone.  It’s not as pleasurable to use but is functionally superior for my needs.  Plus, I love the way it pairs with the PlayBook, more below.

The Pre2, Torch, and the iPhone 3GS all have the same screen resolution.  The Pre2 is a 2.9″ screen, the Torch and iPhone are 3.2ish and are nicer to read for an extended period of time.

I find the Pre2’s calendar and email programs to be vastly superior to the other smartphone platforms.  I find the Pre2 and 3GS to have comparable cameras that are better than the Torch or Android phones.

On the topic of the Cliq2, I find the Android 2.2 device’s apps to be buggy and inferior to the other platforms, the hardware to be shoddier than the Torch, and the screen, despite a higher resolution, to be unusable in the sun, low-quality, and the wide-screen ratio to be less useful day-to-day.  On top of this, battery life is quite poor, certainly not lasting a day.

The app situation is, of course, best on the iPhone and close on Android with lower-quality and cheaper apps.  webOS (used by the Pre2) has some real gems but also has gaping holes in the store.  The lack of a Remember The Milk client in particular frustrates me.  The game situation on webOS is surprisingly good.  The numbers are lower than iOS or Android, but the quality and variety are great.  The BlackBerry Torch has very few fun apps.  The game selection in particular is abysmal.  However, it has a good Dropbox client, excellent GTalk integration, top-notch PIM apps, and a good RTM client.

Day-to-day use (Tablets)

I haven’t found many ways to integrate tablets into my daily work life.  I find 10″ tablets to be about as heavy and large as my 11″ MacBook Air, which is an absolutely fabulous productivity machine.  That said, I find myself taking the PlayBook with me rather than a laptop when I go to a client or to help someone at work in a lab.  The 7″ screen makes it about the size of a 6×9 pad of paper, so it’s easy to keep out of the way.

iPad As far as tablets go, I purchased a refurbished iPad for testing.  I rarely use it except for testing but the battery life is great.  Of course, the app selection is also second-to-none.  The screen is gorgeous, the resolution is nice.  The iPad has great media apps, including Netflix and access to the vast iTunes library.  However, the speaker is very quiet and is quite low-quality.  Perhaps this is something Apple improved with the iPad2.

The iPad is great overall, and, at this point, if someone asks me, I generally recommend an iPad, but I’m just not a fan of iOS’s multi-tasking and I really don’t like the 10″ form-factor.  It’s fine around the house but as I mention above, it makes the tablet about as bulky and large as my MacBook Air to take with me, but lacking a keyboard, it’s far less functional.  On that note, let’s turn our attention to the Asus EeePad Transformer:

Asus EeePad Transformer I love the 11″ MacBook Air, and have found 10″ tablets an awkward size without a keyboard.  Enter the 10″ EeePad Transformer.  As far as I’m concerned, it’s the Android tablet to beat.  It starts at just $399, making it much cheaper than the iPad, it has a great 1280×800 IPS screen, and up to 16 hours of battery life with the optional keyboard dock.  The dock is basically a big battery that transfers charge from the keyboard to the display.  On paper, it is a perfect combination of form, function, and price.  And yet, I find it utterly frustrating every time I try to actually use it at work or at home.  Why?  Android 3.  To sum it up, Android 3 is incredibly rough.  Where Android on a phone is unpleasant to use, I find Android 3 on a tablet to be practically unusable.  There is no global Undo, which I didn’t notice until typing and making mistakes in the bundled Mail program repeatedly, the tablet app situation on Android is pathetic, multi-tasking is bizarre, and the entire interface, while clearly designed for a larger screen, is garish and inconsistent.  Every time I try to use the Transformer, a device which I would love to love, and with great hardware, the software thwarts me.  I’m hoping that Ubuntu 11.10 will work reasonably well on the Transformer.  Until then, it mostly sits idle on my desk at work.

Overall, as far as Android tablets go, I actually prefer the older Archos 70 running Android 2.2 on a device with a 7″ screen.  Android 3 makes better use of screen real estate but phone apps don’t scale up to the 10″ screen as well as they do to a 7″ screen.  Moreover, I find the user interface in stock Android 2.2 to be more pleasing and consistent than Android 3.1 on the Asus EeePad Transformer.  This quite surprised me, as I wouldn’t say that I was a fan of Android 2.2.

HP TouchPad On a happier note, we have HP’s new TouchPad.  The TouchPad finally brings webOS to a large display.  While the device itself feels a bit cheap and the OS could use further optimization, I feel that the TouchPad is a worthwhile investment for anyone interested in an elegant OS made by someone other than Apple.  The TouchPad feels like a 10″ iPhone 3GS.  It is virtually identical in size, weight and thickness of the iPad1.  It has the same 4:3 screen and fits well in most (now discounted) iPad1 cases.  The screen, while fine indoors, doesn’t hold a candle to the PlayBook screen, especially outdoors.

The app situation is surprisingly good on the TouchPad.  It doesn’t have as many native apps as the iPad, but it has far more tablet-native apps than Android 3.  Android 3 can run 2.x’s apps but they don’t scale to the 10″ screen well, and often don’t work well in landscape mode.  I have yet to run in to a similar problem with the TouchPad.  The TouchPad’s speakers are much better than the iPad’s, though they aren’t as loud as the PlayBook.  Again, at 10″ I don’t find the TouchPad to be terribly usable day-to-day at work, but the core PIM apps scale up to the large screen beautifully, so using it is a joy.

If HP releases a 7″ 1024×600 version of the TouchPad, releases their promised OTA update to work out some of the software glitches, and releases updates to the productivity software that allow editing of common office formats,  it would be a very compelling work tablet.

BlackBerry PlayBook I’ve already written quite a bit about the PlayBook.  In short, in daily use it’s by far the best tablet I’ve used.  The more time I spend with it, the more I find ways of integrating it into daily use.  RIM bucked the trend of copying Apple with a 10″ screen.  Instead, they went with a very high-quality 1024×600 7″ IPS screen that is very bright both indoors and outside.  They then coupled the display with the best speakers I’ve heard in a tablet.  The sound is loud and clear enough for me to use in the kitchen, a computer lab, and in my office.  They aren’t as nice to listen to as a full set of speakers, but they’re close.

On release, the PlayBook took great criticism for the lack of native apps.  Reviewers, however, seemed to mostly ignore just how well the PlayBook works in tandem with a BlackBerry phone using Bridge.  I was not a BlackBerry fan but decided to pick up an inexpensive Torch just to test out Bridge.  The implementation completely convinced me that, in some situations, this is a better approach than native apps for quick on-the-go access to PIM data.

The browser that ships with the PlayBook is absolutely top-notch.  The interface allows for full-screen viewing or fluid tabs.  The browser UI is the best that I’ve seen in a tablet.  The entire OS feels and works much like webOS, though it is much faster and more fluid.  The bundled Kobo app works well for eReading, as does the size and weight of the PlayBook.

As far as apps go, the situation is pretty terrible.  Things start off well with a great browser, a decent Podcast and audio player, a way to read eBooks, Flash support, the ability to edit MS Office files, and Need For Speed to show that the hardware is there to make this a good gaming platform, but then that’s about it.  The app selection is, frankly, pathetic.  RIM gave away tablets to anyone willing to make apps.  This sounds good on paper but resulted in thousands of poorly-tested, rushed-to-market, low-quality apps that clearly took less than $500 of developer time.  The situation is slowly improving, but the TouchPad on day one had a far better app selection that the PlayBook does now, three months after release, and is still missing core-functionality such as a working IM program.  That said, it’s still by far my favourite tablet option.  The QNX OS is fantastic, Bridge works well, and the size of the device fits very well with my current needs.  With better apps, the PlayBook would be brilliant.  For now, I would only recommend the PlayBook to existing BlackBerry smartphone users, or to people who are content with the (excellent) out-of-the-box functionality.

Development and testing using an emulator

I may have one device per-platform  but have tested using emulators for most of platforms.  Here are my findings:

iPhone emulators are Mac-onlIy but work well. Before I had an iPhone 3GS, I briefly use the emulator to test websites.  It was fine.  Not pleasant, but usable.

I haven’t used RIM’s emulators.  They tend to be Windows-only.

Android emulators are, frankly, terrible.  They integrate well into Eclipse, but it is a chore to set this up.  Things get worse quickly, as trying to use the emulator is terribly slow and not at all like actually using an Android phone.  I suppose it is useful for making sure your app doesn’t crash, but I find Andorid emulators useless for web testing.

Palm’s webOS emulators, by contrast, are the best.  They use VirtualBox VMs.  webOS is a Linux-based OS, so VirtualBox was a natural.  Both the phone and tablet emulators are fast and fluid.  The command-line Palm tools work with either the emulators or the devices, if plugged in and in development mode.  Being VirtualBox-based, the VMs work on Mac, Linux, and Windows.

Development tools

I haven’t developed for all of the above platforms, unless you count mobile-optimized websites.  That said, I have played with or configured development environments for iOS, Android, and webOS.

iOS, of course, integrates brilliantly with Apple’s Xcode.  I have used it a bit and was quite impressed.  If you aren’t a Mac user, I suppose you could use Adobe Flash CS5 to create iPhone apps.  I hate Flash, so I haven’t gone down this route.  Knowing what I do about Apple’s development process and tight-control over the store and over just accessing iOS devices, I would guess that even using Flash, you would need a Mac a some point to get your code onto a device.  Certainly the emulators are Mac-only.  You’ve got to pay if you want to play.

Android integrates reasonably well into Eclipse and ships with an SDK that provides command-line tools for Mac/Linux/Windows.  I haven’t used the IDE extensively but have configured the environment for the undergrads at work.  It wasn’t super-slick but Google provides good documentation.

HP/Palm’s developer tools are great.  You install the SDK and VirtualBox, and you’re done.  They provide packages for Mac/Linux/Windows and provide excellent documentation for using their development tools and PhoneGap, a cross-platform HTML/CSS/JavaScript package for developing native webOS/iOS/Android/BlackBerry apps using web technologies.  the webOS SDK itself is largely this, as apps other than games are generally written in HTML/CSS/JavaScript using either Mojo or Enyo, HP/Palm’s developer frameworks.  You can use Eclipse to develop webOS apps, though I tend to stick to Palm’s excellent command-line tools combined with my favourite text editor.  I find this development model to by quite flexible.  I even wrote an app that I use quite often.

I haven’t used RIM’s developer tools.  They seem to largely be Windows-centric, though I gather they can be shoehorned in to working on Mac.  RIM’s WebWorks SDK is of interest to me, though I haven’t tested it.

Developer relations

Here, again, HP/Palm to me are the people to beat. HP is aggressively courting all kinds of developers.  Palm has a strong history with the Homebrew community, a group of tinkerers and hackers that extend webOS in unexpected and interesting ways.  HP appears to be actively encouraging this group, which is a great sign.

In start contrast to Apple, RIM, and even Google, there is no such thing as a locked-down webOS device.  There is no need to root or jailbreak your device.  All shipping webOS devices can easily be put into Developer mode, which encourages casual development. Despite Android being Open Source (mostly), webOS is a far more open environment to both use and develop for.

I haven’t used RIM’s development tools and haven’t tried working with them.  Certainly their devices are locked down and they don’t have a great reputation for developer relations, especially with small developers.  The PlayBook device promotion was an interesting attempt to change this, but based on the quality of available apps, I don’t think this could be called a successful experiment.

Apple allows all iOS devices to be used for development, but you have to pay to have apps signed, and iOS won’t run unsigned code.  This results in jailbreaking for those who want to Think Different and use their devices in a way that is unsanctioned by Apple.  I understand the advantages of this approack, and there is certainly no arguing with Apple’s success.  Still, I don’t have to like it, and I don’t have to participate.

Google, with Android, has quite an odd approach.  The software is Open Source, allowing for all kinds of weird and wonderful devices to float around, but how locked-down a device is depends on who makes it.  Moreover, with the rapid growth and talk of fragmentation, Google appears to be locking the development process down, favouring larger device manufacturers, and providing them with early access to new versions of Android.  Android source code may be Open Source, but the process is far from open, and Google seems to be far more concerned about market share than making sure that device owners can do what they would like with their devices.

Wrapping Up

And that’s my view of things as of July 2011.  If you’ve made it this far, please let me know what you think.  iOS is clearly the platform to beat, but things can change quickly.  Just think: Apple wasn’t in this space before 2007.  Personally, despite the allure of Open Source, I just can’t warm up to Android.  Are you a fan?  What makes it compelling to you?  Have you had a chance to use a PlayBook or TouchPad?  What do you think of them?  Am I the only one out that that thinks BlackBerry Bridge is a good idea?

Me, I find that I like a 7″ tablet but that clearly they all need more work.  If the PlayBook had the TouchPad’s app selection, or if the TouchBook was in the PlayBook’s body, that would be a compelling device.  As far as phones go, I’m more excited about what RIM has in store for BlackBerry than what the iPhone 5 might be.  Of course, I have my fingers crossed that HP’s Pre 3 will finally give webOS the hardware to match the great software.

Mostly, I find this an interesting time.  Whether it’s Apple, Google, HP, or RIM, we are clearly moving post-PC.  There are teething pains, for sure, and it will take us years before desktops and laptops are displaced. (And really, when is a technology ever truly displaced.)   I hope that all four of these platforms continue to improve and remain viable over time.  Choice is good.  The PC era began to wither when choice dwindled.  All of these competing platforms may be a pain for developers, web and otherwise, but it keeps us all thinking and allows for new ideas to bubble up to the surface.

These are exciting times to be a systems person, developer, or end-user.  It’s even better being all three.

A quick update…

Yikes. I haven’t posted in quite a while. Things have been busy, which is great.

I have been working on a few posts.  Here’s what to expect in the next while:

  • A review of the Asus Eee Pad Transformer TF101.  Summary:  It’s the best Android tablet I’ve used and I still think it needs a lot of work and that Android is unpleasant to use
  • A review of the new HP TouchPad.  Summary:  It’s a great first tablet effort for WebOS.  The software works very well, the app situation is better than I expected, better than the PlayBook.  Overall, I still don’t link 10″ tablets, so I still prefer the PlayBook.  The TouchPad hardware is decidedly mediocre.  They basically made a 10″ iPhone 3GS.  The good news is that the TouchPad works perfectly with many iPad 1 cases, so you can get nice cases cheap.
  • An overview of what I do to switch relatively seamlessly from Android to iOS to WebOS and BlackBerry OS on a daily basis, just in case anyone else out there cares to do so.
So, that’s what’s coming up.  In the meantime, my wife has submitted her PhD thesis, GoSaBe is as busy as we can handle, we’re looking forward to upcoming shows, and are otherwise doing our best to enjoy the lovely summer weather in this very busy time.
Yippee!

    Living with EL6: Installing Nvidia drivers using elrepo

    First, enable elrepo:

    rpm –import http://elrepo.org/RPM-GPG-KEY-elrepo.org

    rpm -Uvh http://elrepo.org/elrepo-release-6-3.el6.elrepo.noarch.rpm

    Next, install kmod-nvidia:

    yum –enablerepo=elrepo install kmod-nvidia nvidia-x11-drv-32bit

    According to what I read, that should be enough.  However, I also had to disable the nouveau driver by editing /boot/grub/menu.lst and adding the following to the end of the kernel line:

    rdblacklist=nouveau

    That’s it.  Just reboot and enjoy.

    If you’re not familiar with elRepo, it’s pretty cool.  You can read all about it here.  The short version is that it is a helpfui set of repositories that work for CentOS/Scientific Linux/RHEL 5.x and 6.  The repos exist only to enhance the stock EL kernels with new hardware drivers.

    Archos 70 Internet Tablet Review

    Well, after being fairly positive in my review of the Coby Kyros, I am now getting a chance first-hand to see how their warranty process works out.  I won’t go into the details but if you have a Kyros and it breaks, you have to mail the unit to the US ($20CAD) and include a $20USD money order for the return trip.  I have my fingers crossed and in no way blame Coby for either the problem or the cost associated with the repair.  They are a low-price, high-volume company.

    With that out of the way, I have purchased an Archos 70 Internet Tablet while we wait (im)patiently for the Coby to return.

    Archos 70 Internet Tablet

    My overall impression:  At $350, the Archos 70 is very reasonably priced for what you get.  it’s no iPad.  In some ways it’s  better, in many ways it is not.

    Where the Kyros is a sub-$200 bottom-of-the-barrel Android tablet, the Archos 70 is a mid-range model.  It’s not as high-end as a Galaxy Tab or iPad, but it has many of the features that I care about from these more expensive devices, while still keeping well under $400.  In fact, I gather it’s often at $300 these days.

    Me, I paid $350CDN at Tiger Direct.  For this, you get:

    • Pure Android 2.2
    • 1GHz CPU
    • OpenGL-capable graphics
    • 7″ Capacitive multi-touch 800×480 screen
    • A basic but appreciated kickstand
    • A Mini-USB port and Mini-HDMI port, Bluetooth
    • Not much else.

    The Coby managed to swing a rather nice case for the money.  It would have been nice for the Archos to do the same.  However, the Kyros case didn’t stop the warranty call, and I find the Archos’ kickstand to be invaluable.

    In day-to-day use, the Archos 70 is much faster than the Coby Kyros.  The CPU is clocked a bit higher and is a generation newer than the Kyros and this makes a huge difference.  It’s still not as fast as an iPad, but it is about as fast as the Samsung Galaxy Tab.  It looks like dual-core CPUs are going to be the norm from here on out, so no doubt the Archos 70 won’t age well.  Still, for the money it is no slouch.

    The screen is a dust and fingerprint magnet and some people complain about the viewing angles.  I think it looks fine and is appropriate for the price.  If you expect this to be the same quality as a $600 tablet you’ll be disappointed.  If you’re realistic, you’ll be fine with it.

    Like the Kyros, the Archos comes with AppsLib rather than the Android Market.  However, it’s even easier to install Google Apps on the Archos.  It took me 10 minutes to find the .apk and another two to install it, then it was off to the races.  As a hackable tablet, it’s a total win.

    A small but versatile array of ports

    As far as ports go, it has a Mini-USB port that you can apparently use with devices such as USB keyboards.  I haven’t tried this yet, but suspect that it would work fine.  It also has a mini-HDMI port, headphone jack, and power plug.  The power plug looks much like the headphone jack, and I’ve tried plugging the wrong thing in to the wrong spot more than once, so that was unfortunate.  In fact, to me it would have been ideal to have the Archos charge over USB.  Alas, no dice.

    One thing I felt was lacking from the Kyros was bluetooth.  Thankfully, the Archos 70 has this.  This means that you can pair with a keyboard, tether to your smartphone, and otherwise use the device for work on the road.  In keeping with Archos’ hackable past, the device can also dual-boot Linux.  This is something that I will get to when the Coby comes back, and likely means that the device will have a fairly useful future ahead of it.  I will report back on this when I test it out.

    The Archos easily paired with this Bluetooth keyboard

    Android 2.2 works very well on the Archos 70, and Archos seems committed to the device, releasing updates fairly regularly.  The Kobo and Kindle Android apps work well, as do common Android games.  (Yes, Angry Birds works great.)  Thus far, this is the best Android device that I have used.  The browser works very well, and the entire system is quite responsive, even with a paltry 256MB of RAM.  There is a very active community around this device, and the Archos-supported Linux distribution available for the Archos 70 is a very interesting option that isn’t available for anything else that I am aware of.

    Overall, the Archos 70 is a very flexible and peppy mid-range Android tablet.  After evaluating the options, I think it’s the best that’s out there for under $500 and certainly the best under $400.  Archos has a 10″ version, the S101, that is $399CDN with 16GB of storage.  They also sell a version of the 70 with a 200GB hard drive, rather than 8GB of flash. I initially purchased the hard drive version for someone at work, as the flash version was unavailable at the time.  While I understand the attraction of a 200GB tablet, the noise, delays, and additional weight of the hard drive version weren’t my cup of tea.  Still, I like having the option, and kudos to Archos for branching out in this regard.

    The Archos 70, like the Coby Kyros, highlight the virtues of an open platform.  Sure, they aren’t a slick as an iPad, but the price and size are nice.  If you’re looking for a 7″ Android tablet, I don’t think you’ll do better all-around than the Archos 70.  It’s a big step up from the Coby and is still very reasonably priced.

    Coby Kyros MID7015 Review

    Here’s the Twitter version of this Review:

    The Coby Kyros is a bargain at $160.  While not in the same league, It’s one third the price of an iPad and is comparable to the Galaxy Tab.

    The Coby Kyros

    Now, on to the full-length version:

    The onslaught of the cheap Android tablets is upon us.  The iPad is clearly a runaway success, and is the first device to show the value of the tablet form-factor that has been around for nearly a decade.  It turns out that what was missing was a proper, finger-based UI, and the miniaturisation and battery improvements that seem to inevitably come over time.

    If 2010 was the year of the iPad tablet, it looks as though 2011 will be the year of the me-too Android competition.  The Samsung Galaxy Tab is commonly seen as the first real iPad competitor, with the RIM PlayBook and a yet unannounced WebOS-based tablet from HP also coming soon.  These are the big players, the “real” competition to the iPad.  The other side of the coming tablet market is made up of small players crowding the low-end.  The Coby Kyros, along with products from Archos, Augen, and a slew of other fly-by-night companies are covering this well.

    Me, I bought an iPad and returned it.  At $550 plus tax, it came to $621 for the low-end model.  While it seemed like a nifty device, at that price, I couldn’t justify it.  To my way of thinking, the Samsung Galaxy Tab is even worse.  It has a smaller screen, an inferior OS, lower screen resolution, and costs more than the iPad.  Here in Canada, it is $650 ($734 after tax) with no contract, $499 on a two-year $40/month contract.  Plus tax.  Ouch.

    Enter the Coby Kyros MID7015.  It was $160CDN plus tax, so $180 after tax.  This makes it less than a third of the low-end iPad and 1/4 of the price of buying a Galaxy Tab outright.  For that kind of money, I was willing to try it out.  Here’s what you get:

    • A decent pure Android 2.1 OS
    • 800MHz ARM11 CPU
    • 256MB of RAM
    • 7″ 800×480 resistive screen
    • A carrying case, stylus, charger, cable

    Hardware

    The overall build-quality of the Kyros is great.  True, it’s not as slick as either the Tab  or the iPad, but it’s surprisingly close.  It doesn’t feel like a cheap device.  The screen is glass, the back is metal, it weighs about a pound.  It’s about the same size as my Sony e-reader (PR 505) and is virtually identical to the Galaxy Tab.  In fact, I would go as far to say that, aside from Coby’s plain logo at the top, it actually looks nicer than the Tab.  It has just three buttons for the interface:  A combined Home/Menu button at the side, a silver Back button on the front bottom, and a power button on the bottom side.

    The underside also has a USB port for plugging in to your PC, a headphone jack, a MicroSD slot, and HDMI port, and a plug for power.

    Rather than the Tab’s 7″ 1024×600 capacitive multi-touch display, the Kyros has a resistive 800×480 single-touch display.  It’s not as nice, there’s no getting around that, but it is bright, surprisingly responsive, and still looks great.  Like iOS, the Android OS scales the display, so the Tab’s higher pixel density, while visually pleasing, doesn’t offer any real functional improvement.  If you look very close on the Kyros, it’s a bit pixelated, similar to how the iPhone 3GS looks compared to the iPhone 4.

    Having extensively used both the iPad and Kyros, I would say that the pixel density appears similar, while the iPad has a 10″ IPS display, versus the Kyros’ smaller lower-quality display.  It needs to be said again, though, that the Kyros display is surprisingly good.  I have seen many bad LCDs, this isn’t one of them.  It’s also the best resistive screen that I’ve ever used.  I would say it is about as responsive as the Nokia N800 screen.

    Driving the Kyros, is an 800 MHz ARM 11 CPU.  I’m not sure what the graphics chip is, but it is clearly OpenGL-accelerated.  At 800MHz, it’s much faster than the LG Eve (528MHz) that I use for testing.  It’s fine.  Not brilliant, but fine.  The overall experience is not without lags, it’s certainly slower than the A4 powering the iPad.  I haven’t used the Tab extensively.  From what I’ve seen of it, it’s faster than the Kyros, but is still much slower than the iPad.

    Given the price of the Kyros, it far exceeded my, admittedly low, performance expectations.  Games run reasonably well.  There are lags in the UI, but I haven’t seen an Android phone that doesn’t suffer from this.  From my usage of the Kyros and a Nexus One, I would say that the performance is comparable.  I blame the lag more on Android 2.1 than I do on the Kyros.  For the price, you won’t do better.

    The Kyros also only has 256MB of RAM.  This means that running many programs slows the entire experience down quickly.  If you plan to use one program at a time, this won’t be a problem.  Still, there’s no doubt that the Kyros would have benefited from more RAM.

    Like the iPad, the Kyros lacks a camera.  It would never have occurred to me to take picture with a tablet, so I don’t see this as much of a drawback.  A small front-facing camera would have been nice, I suppose.

    The Kyros also lacks a GPS.  Again, this is similar to the low-end iPad.  I’m not a GPS fan, so I consider this a plus, especially given that something keeps turning the GPS back on on my LG Eve, thereby providing someone with more information than I intended, and killing battery life in the process.  Down with Location Services, I say.

    As should be expected on a device of this class, wireless is 802.11b and g only.  One unfortunate piece of hardware missing with the Kyros is a Bluetooth adapter, so you can’t pair it with a keyboard.  Needless to say, I didn’t write this with the tablet’s on-screen keyboard.

    The ports of the Kyros

    Bonus:  A great case!

    The included simple black case from Coby was an unexpected bonus.  It’s remarkable to me that at $160, Coby can include a decent quality case and cleaning cloth.  The case isn’t leather, but it works very well and looks fine.  It is a perfect match to the device, though I may remove the latch.

    Software

    This section will be fairly short.  The Kyros runs stock Android 2.1.  It ships with the very capable Aldiko eBook reader.  This gives you ePub and PDF reading ability.

    The Kyros doesn’t ship with the Android Market by default.  Instead, it come with AppsLib.  This is also used by Archos.  As I understand it, this is due to licensing costs.  I’ve read that with some tinkering, you can add the full gapps (Market, Gmail, Maps etc.)  I haven’t done this yet.  I may, I may not.  It’s not a trivial thing to add, but it’s possible.  In the meantime, AppsLib is OK.  I think a lot of people received Android devices as gifts, though, as the AppsLib market has been up-and-down, apparently due to volume.

    Android 2.1 isn’t the newest release, but it’s new enough.  I have 2.2 running on my LG Eve, and I don’t see much of a difference.  If you want something newer than 2.1, it looks like there are many people actively hacking the Coby Kyros.  As mentioned, the Market can be made to work.  Work is progressing nicely on a Cyanogenmod port, people are looking to add a Bluetooth stack, etc.  Basically, the Kyros is the best of the cheap tablets at the moment.  As such, there are many people working on it.  The future looks bright for tinkerers.  This was one of my reasons for purchasing this device.  My LG Eve would be a terrible Android device if not for the active OpenEtna community.  My guess is that the Kyros will have something similar in the coming months.

    Wrapping Up

    So, that’s the Coby Kyros.  It isn’t without flaws but it’s remarkably good for the price.  If you’re looking for a low-end Android tablet I don’t think you’ll do much better.  If you’re a tinkerer, you’re in for a treat.

    Pros:

    • Great price
    • Solid build quality
    • Pure Android OS 2.1
    • Good size and weight
    • Comes with a case, cloth
    • Decent selection of programs installed
    • Good performance
    • OpenGL acceleration, so games are doable

    Cons:

    • Resistive touch screen
    • No Android Market by default
    • Not Android 2.2 or 2.3
    • No Bluetooth, so no keyboard
    • 256MB of RAM
    • No cameras
    • Not as polished as an iPad or Samsung Galaxt Tab
    • Fast enough, but still sluggish
    • Sketchy support?

    My first webOS app: Poker Run

    I’ve finally done it: I’ve written my first decent HP webOS app. It’s called Poker Run and it’s a simple egg timer for counting blinds. It also lists the small blind values and chip distribution that I tend to play with.

    Launcher icon for Poker Run

    Poker Run: The Application (Click to download)

    My first webOS app: Poker Run (Click to download)

    That’s right, I’ve managed to replace both a post-it note and a $10 egg timer. Woohoo!

    It’s a very basic webOS app written in HTML/CSS/JavaScript. I started with this and improved/fixed a few things:

    • My app allows you to resume or restart the clock
    • I stop the screen from locking or going blank.  This allows it to keep accurate time and always show you how much is left, but it also means that it’s chewing battery whenever the timer runs.

    I should really use Palm’s power management for the timer but this was much simpler.

    Anyway, feel free to download it if you’d like.  It’s nothing fancy but it’s a start.

    Ubuntu Font for Lucid

    Ubuntu 10.10 is out. While I’m planning to stick to Lucid, I love the new Ubuntu font in 10.10.

    Of course, this is easy enough to add:

    sudo add-apt-repository ppa:webupd8team/ubuntu-font-family
    sudo apt-get update
    sudo apt-get install ttf-ubuntu-font-family
    

    The default Ubuntu themes have also received nice, subtle improvements.  These can be installed by running:

    sudo add-apt-repository ppa:murrine-daily/ppa && sudo apt-get update
    sudo apt-get install light-themes gtk2-engines-murrine
    

    And while on the topic of themes, you may wish to add the following:

    sudo add-apt-repository ppa:bisigi && sudo apt-get update
    sudo apt-get install bisigi-themes
