Um… I actually really like the ‘squeeze’ function on the Mighty Mouse. I’ve got it mapped to Exposé’s “All Windows” function, and the trackball click mapped to “Show Desktop” (I thought it was pretty stupid having it mapped to Dashboard since I rarely use it). I should also come out and admit that I have had zero problems with the right-click as well.
On the subject of mice, I was actually pretty underwhelmed by the Magic Mouse. The scrolling was really nice on it, but the two-finger swipe was a pretty poor substitute for squeeze and trackball click functionality that’s gone MIA.
