Normal mice use notches – you pull or push at the wheel until it snaps into the next notch, and the view jumps up or down.
The only problem with this is that it’s a fundamentally different model of scrolling to that used on a normal mouse. The view on-screen moves perfectly with your fingers – after a while it becomes completely subconscious, and scrolling any other way fails to cross your mind. If you remove your fingers while still moving, the content obeys the laws of momentum, flying across the screen before gradually slowing to a halt. Undoubtedly the most used gesture is placing two fingers on the pad and moving them around to scroll.
