I agree with the comments on right click being tricky. You have to re-learn how to use it, which is less than ideal. That said, my MS mouse tracks so poorly on the Mac that I stuck with the Mighty Mouse as it was so much smoother. The result of course is that 6 months on, and I’m comfortable with it. I do still get the odd accidental right click, but for the most part I’m totally at home. The “squeeze” which is really just a thumb click, I can do in my sleep without thinking, nor having to adjust my hand position. So I’m in disagreement over the squeeze, but perhaps I’ve just trained my hand to use it over the 6 months. Should you have to retrain the past 20 years of mouse use? Of course not. Do you have to? Unfortunately yes. If money was no option would I ditch the Mighty Mouse in favour of the new Logitech Revolution VX? Yup. Buy I do like my MM and would love a wireless variant.
