The ViewSonic gTablet is one of the cheapest tablets available with a 1 GHz NVIDIA Tegra 2 dual core processor. Unfortunately the $300 tablet (which often goes on sale for even less than that) has a 1024 x 600 pixel display, ships with Android 2.2 and doesn’t include access to the Google Android Market. While there’s nothing you can do about the screen resolution, there are plenty of fixes for the software situation, thanks to an active community of gTablet hackers.
The latest unofficial update is Google Android 3.0.1 Honeycomb. Basically a group of hackers have taken the recent ports of Honeycomb for the Notion Ink Adam and Advent Vega tablets and brought them to the ViewSonic gTablet.
The custom firmware for the tablet is still in the testing phases. Adobe Flash doesn’t work properly, HD video playback isn’t yet supported, and neither does the camera. But the software does let you overclock the processor to run at 1.5 GHz — something you certainly can’t do with the software that comes preloaded on the tablet.
