@Vitaliy_Kiselev I have bought the newly launch Pipo U1 tablet from China manufacturer which has RockChip (RK) hardware and runs on JellyBean (Android 4.1). To my surprise there is so many problems with the "brain" with this new android software that I need to "Root" (jailbreak) the tablet in order for it to support most of the available apps.

The battery life of this tablet from China is also another issue to consider as they do deplete much much faster than items like Samsung, iPad and Nexus. This would not be an issue if you intend to use the tablet as Monitor/ Controller using DSLR Controller (BETA) from Chainfire if external battery is configured on your rig/ camera gear. But using the tablet by itself like iPad for browsing and playing video is not recommended.

I am very tempting to try to purchase this as the resolution looks amazingly high! I will investigate more before purchasing and do let me know if anyone has purchased this high definition tablet too ok!
