I can tell you I use the mouse on my Thinkpad far more than on any other device I've used, all because it's frictionless and doesn't require me to move my hand.
I do too. But I'm starting to get some pain in my index finger, so I think it's probably time for me to move on. I hear Framework is shipping to my country now...
I agree the discomfort, or after a while, even the pain when using the trackpoint, is something very noticeable on modern thinkpads. I don't recall being this annoyed with the older thinkpads like T61, x200 and all. Or maybe we are just getting old and more fragile haha
