I’ve been using the same mouse since ages now, so it was about time that I got a new one, when I bought the Apple Mighty Mouse today.
That whole no-button thing sounds so nice in theory, but doesn’t really work well in practice: I tend to keep my fingers on the mouse, so when I right click, while my other finger still lays on the left side of the mouse (without pressing it!), it does a left and not a right click.
Quite annoying. Looks like the Mighty Mouse is going back to where it came from again tomorrow.
