I just tried putting the sensitivity on my trackpoint to max, and the cursor literally doesn't move if I swipe my finger across the trackpoint. I have to actively apply downward force for the trackpoint to register. When I use an Apple touchpad, I only ever have to lift my finger if I exhaust the pad's surface area, and the force required to click is lower than what is required to activate the trackpoint.
that is a garbage trackpoint, then. Absolute rubbish. if I turn sensitivity way up on my old IBM A31p and blow through a straw onto the side of the trackpoint, the cursor moves, albeit very slowly.
Back in the day, I would return the entire laptop because of a rubbish trackpoint if it were an IBM built ThinkPad.
