I was browsing kickstarter today and saw this:
http://www.kickstarter.com/projects/...rce-controller

It's a controller that will work on mobile devices as well as OUYA. It's doing pretty well as far as getting backers. However, they advertise that it will work on OUYA. Is there really a need for such a tiny, uncomfortable feeling controller for OUYA? Would any of you guys use it?
