I really like the mice that have a clutch button that lets you unlock the wheel for free scrolling. It helps for scrolling through long documents. I feel like a touchpad scroll wheel doesn't really change the finger motions.

They could adjust the speed of the autoscroll based on how fast your finger moved.
