It takes time to get used to. But it is sooo worth it - I don't need to ever move my hands off the keyboard. I still prefer standalone mouse (but I'm still gamer, so nothing can beat speed & accuracy of dedicated mouse for me), but even when I have plugged it in I sometimes use trackpoint to keep hands on the keyboard. In cramped places (bus, train) I work without problems, and I wonder how awkward would it be with using standard touchpad with laptop in your lap - too close to your stomach, so not much space for hands. Also I don't ever have problems with accidental touching of touchpad - it is simply disabled.

Problem is, there are not many notebooks with trackpoint :/

Btw I can't talk about newest models, but this thing does not change much.
