A bunch of recent Logitech mouses feature an unlockable "free spin" wheel. Basically, you can "lock" the scroll wheel and then it functions as a notched, precise operation for small adjustments. Alternatively, you can "unlock" it and then it scrolls very smoothly and nearly forever. Ideal when you want to move across a large document. It's hard to describe and they do it better at [1].
I would really encourage you to try one mouse with that function. You could be very pleasantly surprised :)
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.
