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.
