The TrackPoint experiment is over. I'm giving up. I'm probably doing something wrong, but it's actually uncomfortable using it as the only input device. Cramp in my fingers and the skin on my index finger feels roughed up a bit. I guess it's good as a backup in case nothing else works or you forgot your mouse; but if I had a choice, I would still use a mouse or trackpad instead. So now looking for a decent mouse replacement.
