REAL Thinkpad users will only ever use the little red stick and disable the trackpad (just joking). But it‘s worth a try, takes a couple days to get used to first.
Real Thinkpad user here, yep using that little red stick since 2006, when I got my first one.
Really feels a bit weird on other laptops, although on those that have two finger gestures it is bearable, or I just end up plugging an external mouse.
Positive side-effect of a disabled trackpad, everyone trying to show you something on your Thinkpad by taking command will quickly stop it once they have no control over the mouse.
