It didn't show up on Best Buy website, but when I got there, new iMacs and Magic Mouse were displayed there. I bought the Magic Mouse and tested it out for the past couple of days. 1) Design is, as expected, gorgeous. Sleek and thin. However, since it's "flatter" then other mouses and even comparing it to the Mighty mouse, using it for a long duration hurts my wrist and hands. This was expected. If I was looking for a comfortable mouse, I probably opted for something else. 2) Click noises are loud. Since it's just one big button, I guess it generates a louder click noises than other mouse. It might not bother some people, but in a quiet environment, it was considerably louder than my other mouses. 3) Cursor (Tracking) speed is slow at default and has to be adjusted with the software. I have Leopard and had to download the 1.0 mouse software. Even setting the tracking speed at the fastest, it's not fast. I have a 24 inch monitor, and sometimes I would need to drag it a couple of times to get from one side to the other. This is good and bad. If you have a lot of room to cover, then it's inconvenient. However, if you're doing more precise work, then this is a good option. But it's definitely smarter than previous mouses. If you move the mouse fast it tracks fast. Slow, vice versa. 4) It's not same as MacBook or MacBook Pro track pad. You probably know from Apple website about back and forward swipe, scroll, etc. Only one finger going up and down controls scrolling compared to two fingers on a track pad. Three finger swipe does not work, and four finger swipe does not work either (No switching windows, expose, etc). Pinching, squeezing do not work on the mouse itself, unless you press control the command key to zoom in and out. Definitely some flaws, but overall I'm happy. Hope next version of Apple Software adds some more features to it.
