I think you just made the decision for it going on my christmas list, I always loved the TrackPoint on my old thinkpad, not having to move hands from keyboard was a nice win and I still occasionally use that machine if I have to do a lot of typing and need to be away from my desk.

It's crazy that I'd pick an ancient R50E (Celeron 1.4Ghz feel the speed!) over my vastly more powerful 17" Vostro but the keyboard really matters.
