I would love to play iOS games on an Apple TV using something similar to a Super Nintendo controller. I have a converted SNES controller that's converted to USB and it's awesome! If I could use that I would be in heaven.
Games which use a lot of finger swiping would need to be changed around to accommodate the different interface but it's something to hope for.
When closely looked at the device it has iphone in the center of controller. Is there a different icade for every iphone model.. HAHAHA.. This is not a product of apple though.
