We already have this. It is called a PC.
Not really. The Ouya has:
1) Fixed hardware platform (very good for developers, users don't need to wonder about compatibility)
2) Default distribution channel out of the box (PC users still needs to install Steam to get games on Steam) and there's no question to the user if the hardware will play any game
3) Default display on TV with a gaming controller (of course, all possible with a PC, but you have to connect and configure it all, plus you can't control the whole system with a gamepad, so you have the hassle of having to use keyboard+mouse on a couch in the living room, which is not always easy).
