I think the main reason for the low renevues is that the games in the store are mostly casual mobile/tablet games. They seem like they are designed to be played in short bursts. Not the sort of game that you'd play for 2-4 hours and lose track of time. OUYA itself is quite decent. I don't quite get the criticism about the UI. It may not be perfect but it does the job of launching your game, no?
