Reaching up to touch the screen is slower than reaching down to the trackpad. Also consider trackpoint.
Skilled users can make the reach and the motion one. You don't need to stabilize your palm on the rest to use the trackpad. Same way I don't need to use F and J for the keyboard (and kinda wish I could remove those annoying bumps)
