Congrats, I got both my OUYAs myself. My backer OUYA finally arrived on the 8th and the one I ordered through Amazon.com (retail version) arrived yesterday.

It's a pain to setup though. Make sure you hook it up to Ethernet instead of playing with wifi because it's a pain. Even with the firmware update.

I'm not a huge fan of the d-pad's directional detection or the responsiveness of the O-U-Y-A buttons. But so far the few games I tried seem to play ok.

Apparently you can use a PS3 or XBox controller as well if you want, but you'd need to design your game to take advantage of these.
