I find that, with my Thinkpads that I don't use the touchpad at all. I find the trackpoint a much more convenient pointing device as it keeps my hands a home row.
Touchpad scrolling is nice. Yes keyboard shortcuts exist for scroll, but I for whatever reason vastly prefer touch-based.
On Thinkpads, there's also the thumb buttons below the space bar that act as mouse buttons. The middle one allows you to scroll with the trackpoint. It's very convenient.
Trackpoints are amazing! I just wish they were more popular. I have had to resort to building custom keyboards with trackpoints to overcome the limited availability.
And they never run out of space!
But when you push it in one direction too long, then let it go neutral, it'll have a bias into the other direction and move there by itself for a few seconds.
And then reset itself and stop, which I always found oddly satisfying
