I have to agree. Being an original Mac user I agree with the "one button is best" because you can never push the wrong button, but also being an X11 user, I like three button mice, it wasn't until scroll-wheels came along that every two button mouse effectively became a three-button mouse, you can't paste without that middle button!
I recently tried to use an original pre-ADB Apple mouse and they are truely awful, how was it that we thought they were neat?
