content: A raspberry pi would be cheaper. Also why a battery? The device is meant to be used with a TV or a monitor, right? So its use case would have a plug nearby. And since you still have to lug around a monitor, keyboard and mouse, it's not to put your office in your pocket. ( smartphones already are solving that one. Hell, my tablet cost half that, has a screen, a better battery life and can run an office suite. All I need is a bluetooth keyboard. ) ( Also a fingerprint reader when one can simply take the SD card away and read it with another computer is ... original, to remain kind )
