Or should I say.... zero-button mice?
I was reading another commentator complaining about Apple's Pro Mouse, also citing that a having only 1 button is very limiting. However, a feedback response made a very good point: Apple can't make a mouse that fits the likings of all people. Some people, like me, like the size, shape, and number of buttons on Apple's current mouse. Some people liked the size and shape of the PUCK mouse (c'mon.. it wasn't THAT bad), and still others like the size and shape of the original apple mice, and STILL others want more than 1 button, some want more than 10 buttons, some want a trackball, and some want bluetooth wireless mice (god that would be nice!)!! So if you DO want multi-button mice, or have some other gripe with the Pro Mouse, go out and buy a third-party mouse, because Apple is not going to be selling 5 different kinds of mice anytime soon.... then you'd have to get the computer and a separate box for the mouse!
As for built-in 2 button and scroll-wheel support in the Mac OS, I would think that is just Apple's software facilitating the ease of getting into OS X. That would be frickin' awesome if they put in their own mouse setup panel or something like that, but I doubt it. They just want to address another one of the gripes of OS X: having to wait for mouse software to be ported.
Just my 2 cents... (don't flame me for not hating the puck mouse!

).
