In my opinion the hated puck mouse is far and away better than the current Magic Mouse, which will will pretty much destroy your hands and give you carpal tunnel guaranteed. The puck mouse had an orientation trough on the button that was easy enough to get used to and, more importantly, was huge enough to be substantive and supportive under a hand. As far as I'm concerned the magic mouse is a class action lawsuit in a box. I used one daily for a few months once and it took years for my hand to recover.
