$51 Android tablet offers 2160p video
Other features which you might not expect from a $51 tablet include Wi-Fi, an HDMI out port,and a front-facing camera. For those who want 3G connectivity, a USB dongle is available. The most interesting line on the specs list is the 2160p video that the tablet can decode. Those who have used the tablet say it is responsive and smooth and the screen has the brightness and color saturation you would expect from a more expensive tablet.
Sure, the ESER A10 isn't the most loaded tablet on the market, but for $51 you can't do better.
