Hi! I am thinking of buying a new mouse, and two amazing mice came to mind. The Magic Mouse, with a multi-touch glass top, and the Performance Mouse MX, which can track on a glass top. The Performance Mouse MX is the opposite of the Magic Mouse; it has ergonomics, buttons, scroll wheel, you name it. The Magic Mouse, in return, has a multi-touch top that supports inertial scrolling. This is where they overlap. Though Logitech technically don't call it "inertia-powered scrolling", hyper-scrolling is pretty much the same thing, except it goes on and on and on. This is included in the Performance Mouse MX. How does this compare to the Magic Mouse's touch-based scrolling?
