I feel like this almost could beat the nexus Q in its own game, since the price point is much lower for a device of similar capabilities and the benefit is more obvious.
The nexus Q includes the sound amp. This doesn't. Not really similar capabilities.
Which isn't to say the Q's inclusion of the amp is a good move overall. It isn't something most geeky people really need --since hooking up a receiver is something learned back from hi-fi systems onward (back when being a sound-system geek was a possible edge in getting laid, so had plenty of motivation/social-currency) or from our dads (who learned it from those hi-fi systems onward)--. And the it doesn't seem to simplify things enough for the non-geeky.
I think Ouya makes Nexus Q and every Google TV box completely obsolete. I am convinced that Google simply does not have the insight to make a successful set top box.
