If you use a trackball you have actual momentum to help keep the cursor moving (and no mouse surface to worry about). I usually use pointer acceleration anyway

If you use a trackball you have actual momentum to help keep the cursor moving (and no mouse surface to worry about). I usually use pointer acceleration anyway because I find it’s more comfortable for me now to make smaller movements, but in the past I’ve used a flat profile and just flicked the trackball when I wanted my cursor on the other side of the screen.
