Exophase
Nothing good will ever come of Exophase.
I have a thought if Android (in one form or another) does make it's way to the P2. Make an app similar to sixaxiscontroler that lets you make touch screen profiles. If I am not mistaken, the way it works is something like this: you take a screenshot of the game you want to play, and then you can assign areas of that screen to hardware controls/nubs. It would be a little annoying to have to do this for multiple games, but I would say it is worth it to be able to use the p2's hardware controls instead of touchscreen. Touchscreen controls would be pretty difficult on the pandora without a super strong hinge.
If Pandora's controls can be setup to look like a standard gamepad in Android then existing apps should be capable of handling this. But I wish developers wouldn't make gamepad-emulation touch controls then not add the small amount of code to support actual gamepads.
