So have some tablets tested and am met with the Iconia A1, and have to say good. The screen size is perfect, 4: 3, better than 7 "devices very easy to read, not pixelated, vivid colors and bright enough very quickly wipe in program implementation No laggs in or start the program nothing creaks or wobbles.... . Battery is also top. On the first day of continuous use approx 6 hours have been run and then had to be about 23% .Akku be first times still really settle. SD card memory can double again. Use the A1 as navigation and multimedia interface in the car and it all works as it should. Absolutely top device
