of the iphone used as a touchpad pointing device? http://uk.youtube.com/watch?v=ybQIcsPtahA a guy uses it as a touchpad in windows. when the iphone SDK comes out - would it be possible to make an app that would allow the iphone to be used as a bluetooth pointing device for macs? and, even better, something you could use a stylus with like a wacom graphics tablet? i don't know much about the iphone's touch interface, but i have read that the regular mac trackpad tracks your fingers in a very different way than a wacom so its not possible.
