btw, I'd be happy to put any PC110-related stuff anybody else might like
to contribute on here too.
I found it very easy to get used to and much better than the dreadful
pointing stick thing, but I already have a Glidepoint on my desk, so
I'm biased. You might find it takes a little bit of practice with the
tap timing and pressure to get it to work consistently. And if you
want to fiddle, there are some tunable timing parameters which affect
how the gestures are recognised.
