Bluetooth Mighty Mouse

Apple has finally released the Mighty Mouse in the bluetooth flavor. This version drops the optical sensor in favor of laser tracking. And, as many other laser mice (especially those from Microsoft), it seems like an updated driver for the Bluetooth Mighty Mouse adds support for zooming while holindg a user-assigned key and rolling the track ball. This feature is currently unvailable on the standard Mighty Mouse, and Apple has yet to release an update. Although, as with many of their products, and simple software update for their wired Mighty Mouse software seems unlikely. Who knows, I may just be wrong.
