I have the ThinkPad TrackPoint Keyboard II. It's pretty good, feels … plasticky but good travel and has a Trackpoint.
However, for me I use the Thinkpad as a "controller" for a desktop, so I get two (well, three, the desktop has two) independant screens and kvm functionality via Barrier (derived from Synergy).
Maybe I'd never want to go back if I tried a mechanical (I got my partner one, but haven't touched it), but I could not go back (way back) to a mouse.
