I bought 2 of these at Christmas
Total Junk, battery life about 2 hours if you are lucky, I took both of them back for a refund.
The battery life on the gtab is impressive....
Back to the hardware, the G Tablet features a microSD slot, USB connectivity, a front-facing 1.3-megapixel webcam, plus built-in Bluetooth and 802.11n Wi-Fi. ViewSonic manages to squeeze all that into a slate with similar dimensions to an iPad and at roughly the same weight. The G Tablet's 3650 mAh battery is said to deliver 8-10 hours of battery life, which tracks closely with the 9-10 hours of surfing potential Apple claims for the iPad.
