One of the biggest failings of the Mighty Mouse is gone, the stupid scrollball on top that was unclean-able. I was actually hoping from a external trackpad, but I will have to look at this. I use a trackball now and find a mouse hard on the wrist. Now if logitech would combine their trackball with a trackpad, I would be overjoyed.
You might want to try out the Wacom Bamboo multitouch trackpad. Seems to do everything the Apple notebook trackpads do, plus you have the option of using a pen.
