Of course, even though the pointing stick on my EnduraPro
sucks, I don't find it slow. On my ThinkPad, I've got the pointer set for maximum speed, and the TrackPoint set for maximum sensitivity, and the pointing stick on my EnduraPro is nearly as sensitive (once you get it off the huge dead zone.)
The TrackPoint on my Model M13 felt like the built-in TrackPoint at
minimum sensitivity, I had to whale on the thing to get the pointer to cross the 1400 pixel span that is my screen in anything resembling a timely manner.
