I really like the idea of those Logitech mice, but having briefly used one, I find that the flywheel mechanism really compromises the middle click. The Magic Mouse also has the advantage of being able to scroll in any direction, which is far more useful than you might think. Finally, it's just nice to have a device that has a minimum of mechanical parts; I feel a lot more confident dropping my Magic Mouse on the floor, since there's not a lot in there that can break.
