Indeed - and real-world testing is the only final arbiter :-)

Nope, that's true, but it *is* learnable.  It has a response that is within
basic human capabilities to model unconciously and to predict, especially when
combined with visual feedback.  I still think messing with it is nasty :-)
Mind you, I always hated those interfaces that "warped" the pointer to the
default button - I always lost the pointer and had to scrub the mouse around to
find it again.
