I like the Magic Mouse, but it's a little on the heavy side (I thought I could use it with one battery like you can with the bluetooth Mighty Mouse, but you can't). Also, the tracking speed is too slow when moving slowly. It seems like if I'm browsing through a menu or trying to get to my dock, my wrist reaches an uncomfortable state because the cursor starts to really crawl along and I'm struggling to get to the end of the menu. Another thing that is sort of bothering me is the inertia scrolling. I thought it would be really smooth like the iPhone, but scrolling web pages stutters a bit and as it slows down, it gets choppy. Also, scrolling through stuff like iTunes library looks bad as well. I turned this feature off for now. I like the wired version of the Mighty Mouse for the weight, accurate and fast tracking, but I'd like the touch scrolling and shape of the Magic Mouse. Hopefully Apple will release a wired version of this mouse. By the way, the Pinch-to-Zoom function would not work on this mouse because when you try to pinch, it thinks you're trying to do 2 finger swipe. That's probably why you still have to use the control key. It's a slick looking mouse though just wish it was a tad lighter and a tad faster at tracking at slower movements.
