I am not.
I have however pre-ordered Gamepop.
Several reasons for this decision:
-It's free if you pre-order before end of June.
-Instead of charging for games, it works on a Netflix model - small flat monthly fee for all games. This is far superior because if I don't like a game I didn't waste any money on it. Means I will try a lot more games for a lot less money.
-Allows you to use your phone as the controller (perfect for all swipe/tilt games) or their controller
-Will be more powerful than Ouya
-HAS iOS GAMES!! HUGE advantage as iOS has a far better library of games than Android.
-Because Bluestacks is developing, (which I currently use on my Android phone and Windows 8 laptop) I'm hopeful their cloud network will allow me to continue the exact same game from my phone to the Gamepop to the phone to the laptop as serves my current location/situation at the time. This is currently unconfirmed but seems likely and THIS is the future of gaming.
-With Ouya I would have to repurchase the same games I already have on other devices.
Android / iOS games work well for me as my playtime is can usually be measured in minutes not hours. Most times I only have 5-15 minutes to play, not enough time to even get into most console games but perfect for this.
