I would die a little inside (ok, maybe that's dramatic :D ) if I was presented a trackpoint-like device but didn't work properly. I had that once - an X1 Carbon 5th gen actually I was using temporarily, struggling to make that useful, because it was too tight (I feel like post-*30 models, you need to break them in, a lesson that I eventually learned) and it would float a lot.

One nice thing about many used ThinkPads at least: trackpoints are usually the one component that are brand new on the device :D
