From what I have read/heard, none of this matters until controller lag issues are solved.
ouya controller lag? it only happens when something is in the way of the bluetooth connection, which also related to the ouya casing causing problems lol.
But seriously with a direct clear path within about 15 feet of the device it's perfect, after that it can get sketchy.
The ouya 2 will most likely have a glass or plastic antenna window somewhere on the case to help, it is a design flaw, you can get around the problem by making the ouya's top plastic lid face towards you if you sit the other side of the room from it.
