Can only improve on the multi touch Apple magic mouse with something a little more ergonomic to a normal humans hand (although it’s a little shame that its not bluetooth, only another USB dongle!)…
It’s so easy to use, there’s hardly anything to learn. Swipe down with three fingers, and all your windows are minimized; do the opposite and they’re all laid out so you can choose one. Swipe down with two fingers and the window you’re working on is minimized, and vice versa. You can also scroll left or right, say, on an Excel spreadsheet, by moving your finger in the direction desired.
An elegant addition: When you perform any of these multi-touch swipe moves, they’re accompanied by an attractive mini-animation next to your cursor, showing little blue representations of your fingertips moving, complete with misty blue trails that fade away. It’s a hint of how well-integrated the drivers are with Windows 7.
