Not OP, but I did give it a chance (couple of weeks) and I just can't seem to get used to it. I have no issue with alternative input types (I frequently switch between anything in mouse keys, trackpad, regular mouse and both finger and thumb operated trackballs), but I was just super inaccurate with the Trackpoint, the pointer kept flying off all over the screen it for some reason. Tweaking sensitivity/acceleration helped a bit, but not by much.

I can definitely understand the appeal - having a mouse on the home row is pretty damn cool - but damn didn't I have a good experience. Using it for a couple days doesn't mean you'll like it.
