This is a terrible idea. An Android-powered console that lets me, uhh... play Angry Birds on my TV? Other crappy mobile games?
It doesn't make any sense. An Xbox console only costs $200, and already has an established software library with an online store. I can MAYBE see this being useful for playing emulators... but I can already do that on a cheap HTPC. Hell, I can do that on a $25 Raspberry Pi. Why buy another proprietary console?
Yeah. That's not very 'open' at all. The main tenant of this console is already compromised.
If you want an 'open console', then buy a mid-range gaming PC and hook it up to your TV. That's as open as you're going to get. You might respond, "but the average consumer doesn't do that! The OUYA is much more intuitive and user-friendly!" Well, alright; but it's still not open. If you want to turn it into an open console, you apparently have to root it... which throws the whole 'user friendly' thing out the window too. The creators here are being pretty dishonest.
I'm baffled they have so much money already. Good for them, I guess. Maybe we could use some more variety in the console market. I won't be backing it either way.
