(Clearly not.) But nevertheless, this is a very interesting article about Fitts' Law and how interface design should be affected.

Some of the assertions seem...unfitting, though: for me, moving the mouse to the bottom is the most annoying move, not the least: the mouse
has to travel beneath my palm and wrist (I tend to control the mouse with my fingertips and a bend of my wrist and rarely ever lift my elbow off the desk.) Moving to the top I just extend my fingers, so that's faster.

But then I'm weird: I have the mouse on either side, with some bias to the left -- but I'm somewhere between righthanded and ambidextrous otherwise, I switch between two different keyboard layouts every day (german at home, english at work) and so on.
