Is there a problem with Android Gaming? Are touchscreens are pretty rubbish? Is it just me who feels AngryBirds seemed to add a randomness factor to trajectories and got away with it because no-one could tell if they were being accurate with a finger?
They could go after the Wii market. More accurate gaming will require new controllers which means new game code and at that point, you're probably better off going with Steam.
Do we need a hardware card for games? Something to handle multiple bluetooth joysticks/paddles/gamepads/music? Are we better off using wifi for that?
