I had my doubts but got used to the Magic Mouse quickly.
The key to the Magic Mouse is to go out and buy a set of rechargeable batteries and charger (Radio Shack is where I got mine). Then the battery hog issue stops being an issue. I am on my 5th battery/charge in less than 3 months
Yah seriously though. It eats batteries like a mouse eats cheese. I like it, its invaluable to me in Photoshop. The gestures also compliment my workflow incredibly. I can activate suxpose with a tap up top and then go through 10 power point windows, photoshop, and my browser.
It's a cool mouse, well worth the 70 bucks. It's well built too and seems to last. Good solid Apple product in my opinion. It did take some getting used to, but I have been in love since first swipe. ha ha ha
