The controller hasn't changed since the mid-1980s. Almost all the game console makers make the same damned controllers with exception to the Wii there's been almost no innovation.
It's about time to rethink the standard controller design. I'm not talking about game-specific controllers, like the gun or joystick. I think there needs to be something more attached to actual human body movements.
I know this project was about an open game console, but I think this creates the opportunity for innovation in hardware accessories (i.e. the controller). I think we could do a lot better than the same old formula:
Up+Down+Left+Right A+B+X+Y R1+R2+L1+L2 Select+Start (ALL BUTTONS)
