Review: The Viewsonic 10-inch gTablet

The gTablet is Viewsonic's entry into the sub-$500 Android tablet market.  While there won't be any shortage of cheap Android tablets, readers, and toasters (we have to beat the PreCentral guys in the race for the first smart toaster!) come this Friday, a few stick out hardware-wise, and the gTablet is one of them.  Just so happens that I got a few days of one-on-one time with a gTablet, so what better way to play with it than to give it a quick review.

Normally, none of us here would dare review a device we haven't put through the paces, but this one's a bit different, because this is much more useful before Black Friday than it would be after.  Hit the break to see the whirlwind review of the gTabet. Special thanks to Chip!

The Hardware

First, let's take a quick look at the gTablet itself.  The easiest way to do this one is with a video, and I'm always one to take the easy way out.

Yes, it's a slick package.  The one bad thing to be said about the hardware is the screen's viewing angle.  The screen looks great, as long as you view it head on.  if you don't, it's unusable -- not just bad, but impossible to use.  You need to know that going in.

HDMI out is nice, let's hope Viewsonic follows through with the dock and cables for this one.  And the full size USB port (you can plug a USB keyboard into this thing and it just works!) is pretty sweet.  The rest of the specs aren't too shabby either:

  • 1GHz NVIDIA Tegra 2 - Dual-core ARM Cortex-A9 CPU
  • 512MB DRR RAM
  • 16GB internal memory (expandable up to 32GB via SD Card)
  • Android 2.2 (Froyo)
  • 10.1" TFT-LCD with LED driver system and 1024x600 resolution
  • OpenGL ES 2.0
  • 32-bit LP-DDR2, DDR2
  • S1080p H.264/H.263/ VC-1/MPEG-2/4/WMV9/DiVX 4/5 Video Decode
  • 1080p H.264/MPEG-4 Video Encode
  • Supports multi-standard audio formats, including AAC, AMR, WMA, and MP3
  • 1.3-megapixel camera
  • WiFi : 802.11 b/g/n
  • Bluetooth: Bluetooth 2.1 + EDR
  • Built-in 2 x 1-watt stereo speakers
  • USB 2.0 (Slave)
  • Mini USB 2.0 (Host)
  • 3.5mm stereo headphone
  • Micro SD
  • Dock for HDMI/Headphone/USB (optional)

Yes, that's quite impressive for $400.  But don't get too excited just yet -- lots of great hardware is killed by poor software.  I'm not saying the software on the gTab is the worst you'll ever use, but it will be right up there in the top five.  Have a look and see, I tried to show the whole enchilada, unedited, so you can form your own opinion.

The Software

There's a little bit of good in there, but a whole lot of bad to dig through to find it.  The gTab plays media great.  The music player is an improvement on the stock Android player, and it plays just about any video you can throw at it -- very well I might add.  The applications themselves are designed well, offer just the right amount of information for the increased screen size (this is no phone UI ported over, it was designed with a tablet in mind), but they are terribly slow.  Things that just happen on a top tier Android phone seem to take forever to start on the gTablet.  It's completely up to you to decide if you can handle the laggy UI until (hopefully) it gets updated to a more usable state.  So far, Viewsonic has done well with those updates, but who knows what the future will hold.

The battery seems fair.  Having a standby mode helps, but even a good five or six hours of tweaking, flashing and fooling around didn't kill the battery.  You'll use less than half of the battery playing an H.264 encoded full-length movie.  The Lake House to be exact.  You married guys know what I'm talking about.


The gTab gets a perfect five-star rating for unlocked, hackable hardware.  No secured bootloader, no NAND lock, put a correctly structured zip file on the internal storage and flash it.  Thank you Viewsonic, for treating this like a home computer instead of a locked up smartphone.

The hardware itself is capable, even running on an OS (Android 2.2) that doesn't support both cores of the Tegra2 chip.  Have a gander.

Linpack scores

Quadrant scores

Quadrant advanced won't run on the gTab, so we get no individual scores.  It blows through the tests, except for the I/O portions. But we can fix I/O benchmark scores.  A little hacking (Galaxy S remount lag fix treatment) will shoot these scores to:

Hacked quadrant

Once some kernel source gets released (ahem, Viewsonic) things can only get better.  Pretty interesting now ain't it?  Tegra 2 phones on an OS with proper support are going to be sweet indeed.  We've got a super easy set of instructions for those who want to monkey around with it, check it out right here in our forums.

So you've seen the gTablet, warts and all.  You'll have to decide for yourself if it's a worthwhile purchase.  My suggestion is to pass, unless you want something to tinker with.  Wait for proper software support, that takes advantage of this great hardware.  But if you do like to tinker, it doesn't take much to go from what you see in the video to a pretty darn functional 10 inch tablet that does this:

  • Good tablet, but galaxy tab still better
  • $379.99 @ Sears
  • $279 at Sears Outlet. I checked at a local one and they are supposed to have it during Black Friday.
  • It's all about the Angry Birds! Aside from that if someone can port a stock android ROM on there, then I'd consider it. That Viewsonic UI is absolutely dreadful.
  • CM 6.1 is now running on it.
  • It's on like Donkey Kong one the rooting scene starts to mess with this. Just bought an iPad, but may sell it and get this if the software issues get fixed.
  • Here ya go running TnT lite by roebeet
  • The hardware seems to be pretty good. To me that's more important than software because it can't be fixed with an update. If the update rhe other day took this tablet from unusable to just slow I have no doubt that the next update could make it that much better. The real gem in this tablet to me is what the development community can do with it.
  • Galaxy Tab has less than this and costs more, Tegra 2 > hummingbird. 10.1 inch > 7inch. Full USB support > no USB support. Honestly though Samsung made the Tab great with allowing the market and everything it doesn't even matter.
  • But its slow as shit!
  • Samsung Galaxy tab is cell phone hardware with a bigger screen. G tablet will get better with future OS upgrades.
  • Tegra 2 is greater than Hummingbird, but there hasn't been a Tegra 2 properly introduced into the tablet and smartphone space, some have tried. So far I have seen Tegra 2 get disappointing results in the execution department.
  • Hardware looks IMPRESSIVE. But the software on this thing makes a netbook look like a blazing piece of computing power.
  • Got an EVO but never rooted. So if we root this, doesn't the software not matter?
  • I bought this tablet and took it back 3 days later , was just horrible !!!!!! Worst I have ever seen or used !! Dont waste your money
  • The tab is crappy but after root and CM 6.1 she screems. Market is functional and flash works. Excellent buy after you "fix" it.
  • Viewsonic has a firmware update on the G-tablet. Can you comment on software improvement on this update? It's been widely reported online in the past few weeks that the G-tablet has many software problem. I am eagerly to learn whether the new firmware fixed most of these irritations.
  • Not Impressed...
  • There is no shortage of available reviews of this device on youtube with the device performing flawlessly. Every transition is fast, instant, fluid.. I don't understand why your gtablet is so slow? possibly just a dud? Given the other reviews, I think this is a poor representation of the capabilities of the device.
  • I've handled one, and it performed a lot like Jerry's unit.
  • I am sold on the hardware part.
  • AC,
    PLEASE get rid of the background music. On the software review, it's too loud and kills the audio demo during the review. Reviews don't need background music in order to be informative pieces. Thank you.
  • Forgive me if I am being naive, but why do these manufacturers have to skin these devices to the point they are nearly all around worse than stock android. Is there a problem for them to leave devices like this stock?
  • I just toyed with the gTablet at OfficeDepot and was able to easily install Angry Birds from the webiste which basically downloads the .apk file and one downloaded you simply click on the downloaded file and install it. No rooting or trickery.
  • When you buy it, it comes with the game.
  • What got me to buy it was the battery life. I needed something to last me all day at school. And to take notes on.
  • new to Android and just bought the gtab. Is there a way to load Android 3.0 on the gtab yet ?
