I recently switched to Mac when the mini was introduced. I have been working with PC's or equiv. for the last 20 years. I have used all kinds of "mice" during this period. I always preferred the Logitech two button trackball. The last few years I have experienced considerable pain in my wrist and hand. Since using the Apple BT one button mouse, all the pain has disappeared. Also, I no longer notice any inconvenience with the Apple mouse. But then again, as I mentioned in a previous post, maybe I am just getting old.
