I was pleasantly surprised by ASUS' Eee Pad Transformer. In a sea of clones, ASUS managed to produce the first Honeycomb tablet that was truly different in more than just styling and software preload. As the first PC maker to build a Honeycomb tablet, ASUS brought some new perspective to the game - which had previously been dominated by players from the smartphone industry.

From a hardware standpoint, the Eee Pad Transformer was nothing new. Its mostly plastic construction helped keep costs down but ASUS managed to get the overall device to feel pretty decent, aside from some creaking. The form factor itself was quite pleasant, the Eee Pad felt good to hold. Internally driven by NVIDIA's Tegra 2 SoC, performance and battery life were similar to other Honeycomb tablets we'd reviewed. Not as good as the iPad 2, but still better than most notebooks/netbooks. ASUS also shopped at the right places for the display panel: its quality and characteristics rivaled those of the iPad 2. In fact our only real complaint about the Eee Pad was that its display was far too glossy. It's not a huge problem indoors but held up against rival Samsung's Galaxy Tab 10.1 or the iPad 2 and it is distracting.

By avoiding an aluminum chassis, ASUS was able to build and sell the Eee Pad for $399 - making it the cheapest Honeycomb tablet on the market today. Price alone isn't what ASUS was leaning on however. The real selling point of the Eee Pad is its ability to transform into a 10.1-inch netbook via an optional keyboard+battery dock. With a street price of $150 and often available in more affordable bundles, the dock gave us a peak at one potential future of computing. As a standalone tablet the Eee Pad held its own against the competition, but when docked it became virtually indistinguishable from a low end PC. Apps like Polaris Office give you access to read/write Word and Excel documents, while the full keyboard and mouse make typing long emails or even articles so much better. It's not the perfect PC replacement as a number of file types are still not supported (Polaris won't let you so much as view a .pptx file) but it's amazingly competent for an OS with its roots in smartphones. The extra battery life you get from the dock was also much appreciated. As a glorified typewriter, the combination would easily last you on a flight from California to Japan (or LA to Taiwan like I'm on today). The solution has potential, but it also has problems.

I ran into a number of hiccups with the setup in my review of it last month. Some of the issues were of course due to the early nature of Honeycomb, while others were just problems with ASUS' implementation. Just yesterday ASUS gave me a drop of the OTA (over the air) update that's coming to all Eee Pad users on Monday. This update will give the Eee Pad Android 3.1, the long-awaited point release to Honeycomb that is supposed to fix bugs, improve performance and even enable some new functionality. Xoom owners got access to the update earlier this month thanks to it being Google's launch device for Honeycomb, but ASUS isn't far behind.

I haven't had a lot of time with the update but I wanted to go over some of the enhancements and give you Eee Pad users a preview of what's to come on Monday.

Improved 3D Performance

Just as we have different CPU/GPU configurations for notebooks and desktops, in the future I'm expecting to see different SoCs targeted at smartphones and tablets. Today however, the two share a common architecture with most SoCs optimized for the larger portion of the market - smartphones. The current one-size-fits-all approach has consequences for tablets. NVIDIA's Tegra 2 for example is clearly built for smartphones with either a 800 x 480 or 960 x 540 display resolution, however it's used in tablets running at 1280 x 800. With nearly twice as many pixels to render it's not surprising that while the Tegra 2 performs exceptionally well on a smartphone, its 3D performance suffers on a high resolution tablet. It's no different than buying a PC video card - a GPU that performs well on a 1680 x 1050 display may not be able to drive a 2560 x 1440 display.

In our first Honeycomb review I complained that some UI animations and transitions lacked the smoothness that I expected from a fully GPU accelerated UI. Google argued that part of the reason was the display resolution, but it also conceded that there was still room for improvement in drivers. Android 3.1 gives us that improvement.

The performance impact is easily seen in our standard 3D benchmarks. Let's start with GLBenchmark 2.0:

GLBenchmark 2.0 Egypt

The Egypt benchmark saw a 54% increase in performance. I don't doubt that some of this performance improvement was NVIDIA simply optimizing for the benchmark, but a lot of it translates into real world performance improvements as well.

GLBenchmark 2.0 PRO

GLBenchmark PRO doesn't show any increase in performance by comparison, perhaps indicating that we'll see a greater increase in OpenGL ES 2.0 workloads.

We've added two new tests to the suite from Rightware: Taiji and Hover from the BaseMark ES2.0 suite (basically the updated version of 3DMarkMobile):

BaseMark ES2.0 - Taiji

BaseMark ES2.0 - Hover

3D performance improves in both tests by 24% and 10% respectively.

The impact on GPU performance isn't limited to just 3D games, the Honeycomb UI is now noticeably quicker. Everything is snappier, which implies more than just a GPU performance improvement but the other part of that is an improvement in UI frame rate. Swiping between home screens is pretty similar to 3.0.1, but the experience is far more consistent. While 3.0.1 was more likely to chop, 3.1 seems to be more resistant to slowdowns that impact UI speed. Renegade background apps can still ruin the experience - caching songs from Google Music in the background made the Eee Pad extremely slow.

Calling up the app launcher is still not smooth, but boy is it smoother/faster than before. Even details like the circle animation when you unlock the device are smoother on 3.1.

The iPad 2 still does a better overall job of giving the UI thread high priority and keeping the interface running at full frame rate, but Android 3.1 takes a step in the right direction. If you were unhappy with the UI experience on 3.0.1, the experience with 3.1 is a lot better but still not perfect. If you were happy with 3.0.1 however, prepare to be even happier.

    ProDigit: that's just the price gougers ... got none for $399 usd.

    Anand, which device(s) are you bringing with you to Computex? What is your "go-to" device on a long-haul trip?
  • Sagath - Saturday, May 28, 2011 - link

    I believe he has said its a SB based MacBook Pro 15" in other articles.
  • jjj - Saturday, May 28, 2011 - link

    I wonder if we'll see a Kal-El netbook from Asus at Computex or just Tegra 2 and if it will run Android or Chrome OS.
  • Rayb - Sunday, May 29, 2011 - link

    I believe that there are a few manufacturers that have sampled Tegra 3 since the end of february and in line to deliver new products this year with the new chip. Tegra 2 is already outdated since it took so long for manufacturers to adopt it, with Kal-El bringing 5x the performance I don't doubt we'll see it at Computex in different configurations.

    I still confused why these things are rolling out with Android OS and not Chrome OS. It just doesn't make any marketing sense. At some point either Chrome OS is going to evaporate (which its such a big hit now I wouldn't be surprised) or the two are going to collide.

    The majority of the john and Joan Public don't even know that Chrome OS exists or/and are just confused because it has the same name as the browser.

    They should have called it "Chrome Extreme", "CS-winning" or "Co za asy".

    Just like Android 1.0, I'd say the tablet version needs a few revisions before I'd bother recommending it to someone else. And the tearing in that scrolling performance is horrendous.

    Honestly, if Google just spent one major revision only improving performance of the current system (scrolling, graphical animations, fixing bugs, streamlining UI), i think that'd be perfect. It's the persistent problems that I just know Google engineers must be aware of that need to be fixed sooner rather than later.

    You say they need a few revisions, but iOS has had a couple revisions and it still does the same type of thing... it just manifests itself differently (as Anand points out). So it's disingenuous to act like Google engineers are just incompetent or rushing the product.
  • robinthakur - Tuesday, May 31, 2011 - link

    No iOS is generally smooth as. All google Android handsets and Tablets i've used have suffered from the weird scrolling since I started using them. This lack of smoothness is jarring coming from an iOS device and is the most prominent reason why I would never switch until it's fixed - It just feels like they don't care about detail or user experience as it stands or they are trying to cater to types that don't notice the difference.

    You will be even more surprise if you have to send your tablet back to Asus for repair. I did. The second day the sound was gone on the brand new tablet. Called the customer service and they identified the problem with a faulty sound card. Brand new under warranty, but THEY REFUSED TO PAY FOR SHIPPING. I had to shell out $30 just to ship it to them when it is all their fault.

    I should have bought an Acer A500 instead. If you consider attaching a USB keyboard instead of the Asus dock, and the hidden cost of repair shipping, I'd save myself almost $200.
