It's underspecced and can't do anything different to your laptop or desktop PC.
If it worked, it would be an acceptable deal for $100.
That's why it's not an acceptable deal for $100.
Notably, the controller completely punts on handling touch. It doesn't even have gyros. It would have been better to punt on the controller, and work on making PS3 controllers work properly.
When I had my Ouya, a bluetooth keyboard would inevitably work its way towards being controller #1. Then you couldn't play any games until you unpaired the controller and the keyboard, and repaired the controller. And the PS3 controller support was spotty at best, as well. The launcher would crash, and games would crash, and games that were on the launch poster weren't launch titles, and and and. The most notable "and" is that the development was completely closed (in spite of the Ouya being billed as "Open") and users have to wait for updates.
I was and remain an outspoken supporter of the concept. It's too bad Ouya failed so hard to anticipate the future. If they had worked with Google to create a controller standard instead of striking out on their own, they might have secured a place for themselves in the Google Play gaming ecosystem.
Nothing in particular is stopping them from going that way, except perhaps competence. But if there is a sequel, I suppose it will tell.
