I absolutely love using my Magic Mouse. Whenever I get on someone else's computer I'm trying to go back and forth on web pages and desktops with the mouse.
the sideway scorlling seems like the only worthwhile addition to me, other than that, i kinda like the feel of physical buttons and scroll wheel under my fingertips
I used to think the same way, and when I bought an iMac about 3 years ago I just stuck to the Magic Mouse that came with it. I will never go back as long as I'm using a Mac now - it just became part of my workflow so seamlessly that using a regular mouse is out of the question. I get just about all of the gestures that the trackpad offers with the precision of the mouse. I love it.
