And even the T14s (gen 1) has a "cheap" trackpad with a plastic foil on top instead of a glass surface. The day before yesterday I did the upgrade from foil to glass on my T14s and it isn't the big leap I was hoping for. Sure, friction went down a bit but precession and gesture detection were good before already. The same upgrade on a T480s was a bigger improvement. Compared to my MacBook Pro (M1 Pro) the trackpads of my ThinkPads are always worse. Overall I'm in the same situation as the author of the article (if you substitute Arch for pop!_os with Cosmic) and totally agree with him.
