I can't tell and maybe it's because it's late if you're trying to be rude and condescending or not, but I'm sure it really is as easy as you said, but no I've never rooted anything ever on any device nor have I hacked any console to do anything 'interesting' too. I am from the US, but I'm not sure why being Canadian would be a bad thing on Amazon with $75 in credit.
At this rate as I said, I got that cable and can pop my tablet into the TV which kind of solved the problem. Beyond that I'd really have to dig into the nature of the Ouya to see if I'd find enough utility in it personally between its unique games that don't leave it, other apps too, and perhaps that XMBC media center setup as it could make for a nice MP3 player I suppose.
So you root the Ouya with those steps, then what's it take to fire up Google Play? Is there a rooted app for it, and then you just have it dump the games to the Ouya? Like I said it's not off the table, but I'd just need to go dig some more now that I have that tablet cable. I could definitely see since the controller supposedly sucks(whatever) using the Wii U Pro, PS3 or even the moga pro if that will work right(read conflicting stories.)
