We all know and love the multi-touch interface on iPhone but what about using it on other devices? Multi-touch was rumored to be included in the new iMacs, but that didn't materialize. It has also been suggested that multi-touch could show up in an upcoming refresh of Apple's monitors.
If you're paranoid about marring your beautiful glossy screen, fear not fair citizen. This version of multi-touch will allow you to use multiple finger gestures on an extra-wide trackpad, instead of touching the screen.
