A good friend of mine actually got one. He mainly got it for emulating games, but actually ended up playing a lot of the games made for Ouya itself, as well.
I've tried it at his place, and I'm certainly getting one for myself. The only thing I didn't like about it, was the shoulder buttons on the controller(the triggers were fine, though). Because of how they are placed, and the edge that is there. But that might just be something I'll get used to. In my opinion, it's certainly not a deal breaker! I pretty much fell in love with the thing, so yeah, I'm getting one!
