FWIW both these thinkpads I have (T430u, and the new Helix) the touchpad settings were perfect from the start. the T430u singlepad has a plastic, horrible feel (it has tiny braille bumps) and after awhile your fingertip starts to feel funny.
the helix has a nice smooth matte plastic singlepad. not anywhere near as nice as the HP envy series glass touchpads. those are perfect.
