I am growing increasingly unhappy with Thinkpads in general, but as far as I know there is no real alternative for TrackPoint users. There are some that have a TrackPoint but they lack three physical mouse button that are in reach of ones thumbs.
Why are you growing unhappy? (I have a X1 Extreme Gen 1, and Legion 7, and Legion 5 Pro, so I'm curious)
A few things. The newer TrackPoint caps are not good. I actually had to order some 3D printed one from some Japanese guy. Also my Thinkpad T14 is throttling to the extent that I had to install tools [1] (?) that fix this problem. Battery seems to be bad as well. Intel by the way, I wanted to have Thunderbolt for an eGPU.
