Unfortunately I have to agree. I hate the Mac UI with a fiery passion, the mouse doesn't do what I want it to do. And they really are overpriced.
I'd go crazy without all my multi-touch trackpad gestures for a long while if I had to switch my main machine back to a PC. 2 finger vertical and horizontal scrolling, 3 finger swipes to go forward and backward in the browser, 4 finger swipe up to make all the windows glide off the screen to view the desktop, 4 finger swipe down to make all the windows shrink and display all open windows on the screen to switch windows.
