Use iPhone as a MacBook-style trackpad?
Hey guys! I am a PowerMac G5 user with Leopard and an iPhone. My hardware is pretty old, I have an old mouse that lacks the ability to scroll, much less do a two-finger scroll or resize like my friend's MacBook. My question is, is there any way to use the iPhone as a trackpad for computers? It could be connected via wi-fi or through USB and used like a laptop trackpad in order to control the mouse! Better yet, someone could even try to develop the accelerometers to make it perform like an actual mouse and a trackpad all in one!
This might be a crazy idea, but if it's possible, it's probably one the most useful things I've heard of for the iPhone... I'd like to talk to some developers about this idea! What do you guys think?
