What made me give up the TrackPoint was.. a new Thinkpad. It has simply gotten so difficult to use with the T460s, possibly due to the high screen resolution (I had the 2560x1440 variant). Increasing the sensitivity did not feel right, and it sometimes have too much inertia (pointer keeps moving after I release the nipple mouse). I hurt my fingers trying to use it at a low sensitivity. Eventually I just gave up and switched to the touchpad for most use cases. More recently, I got another Thinkpad with a lower resolution, and it seems to be much better, but I'm no longer that accustomed to using it anymore. Maybe I should consider trying it again.
I like them even on newer ThinkPads just as much, and I've used them on an X1 Carbon with a 4K screen (I do use Linux exclusively, so maybe it's different on Windows). One thing I have noticed is that as the trackpads have gotten bigger, hitting it with your palm becomes much easier, despite any software protections against that. I generally disable the touchpad on newer models, something I never have to do on my old trusty T420s.
I agree with the grandparent and disagree with the parent. My X220's Synaptics TrackPoint is very responsive and natural, and I can get my work done (though the TrackPad is poor). My X1 Carbon Gen 7's ELAN TrackPoint randomly increases and decreases in sensitivity, I can't get used to it, and I end up using the TrackPad instead (which is decent but I still prefer a good TrackPoint).
I also agree. The whole reason a got an X1 Carbon was that I figured Lenovo couldn't screw up the trackpoint or keyboard too much. I was wrong. The trackpoint frequently meanders off on its merry way and the keyboard is unimpressive and now has some keys which don't work. Even though the screen and sound are a big step up, I'm back on the X220.
Naturally, like every device nowadays, they've traded thickness for function so it is also impressively thin. If I enjoyed using the keyboard, I would also be pleased with the battery life.
I have the same problem. For some weird reason my company-provided X13 Yoga's trackpoint just doesn't feel right. I tried adjusting it but I eventually gave up and switched to trackpad (I don't use the laptop that much anyways).
That one doesn't even have a huge screen resolution (1920x1200 I think) so I don't quite understand what's wrong. Maybe some change in parts?
