A colleague of mine has that and the trackpoint on it is useless. I tried it and it feels super stiff, no acceleration, and the mouse buttons are very hard to press, too. The keyboard is very nice if you like buckling springs. Buy their normal keyboards if those are your thing, but don't buy the EnduraPro. It's nothing like a ThinkPad trackpoint.
Sounds like it uses TrackPoint II, which was an earlier iteration of the TrackPoint as we know it. I have the first laptop I ever used, a Thinkpad 350C and it has this earlier iteration. The feel and caps used were very different.
