Some old models (X201 or X201s iirc, so around 2011) could be configured without a trackpad. A 12-inch notebook with a 7-row keyboard and trackpoint is fantastic!
I love the trackpoint as well - when I'm on my own system
I have configured hotkeys, a launcher, and qutebrowser, so I can do almost anything without needing a mouse.
Unfortunately, the company I work at is a huge MS fan, and I've found it very hard to use a workflow that does not depend on fast and precise movements with the cursor - so I switched back to the mouse, unfortunately.
I agree, but a trackball will give you the fast and precise movements you say a trackpoint doesn't give you. You'll also be able to move your hands less compared to using a mouse.
