Eek, I don't think anyone's going to buy in to the ecosystem.

I have an Ouya and enjoy it. Got it for about 80 bucks at Target and have purchased several indie games for it. There's no real "AAA" titles on it, but if you're looking for a nice cheapo game system with some nice party games and some pretty good shooters, then it's a hell of a lot cheaper than shelling out 400+ bucks for a brand new gaming system.

It runs emulators well, too. So if you have a pile of roms and want to play it on the big screen, then Ouya rocks for emulation as well. There are ports of Plex, XBMC, and other nice apps, too. I put a list of games available in the related links for you to check out.
