No tapping, have to press the mouse buttons for any clicking. I can not clearly distinguish and say what was the bigger problem of the two. I use the trackpoint in my Thinkpad X60 quite a bit, which is supposed to be some kind of state-of-the-art trackpoint I think, and after two years I still don't like it. I'm far more exact and faster with a mouse. But I can say the pointing stick in the Endurapro is another (worse) league alltogether. I can imagine one could grow accustomed to the dead zone where you move the stick and nothing happens, but once it starts reacting it's hard to control the pointer speed. A little more pressure (and it needs a lot in the first place) often results in the speed jumping from slowest to maximum instantly. Maybe this can be made better by setting the OS mouse preferences to maximum sensitivity as some suggested here, but I think this is just an ugly workaround as it makes a real mouse used in parallel de facto unusable. And it still can not hide the fact that it's *not* a trackpoint but some cheap lookalike.
In my case the collision with the surrounding keys made the situation much worse, but even without that I would have settled for a return in exchange for a model without this damn pointing stick. There's just *no* joy in using it. I think. IMHO and all. Trackpoint enthusiasts - feel free to disagree!
