[citation][nom]hellwig[/nom]LOL. It only took what, 21 years to adopt a proper mouse (going from the first Mac back in 1984)? That's a pretty good response to emerging technology if I ever saw it.Personally, I can't stand the limited functionality of 3-button scroll-wheel mice anymore. Give me at least 2 additional thumb buttons!!![/citation]
The first Xerox mouse had a single button, and Xerox PARC also designed a three-button model, but reduced the count to two for Xerox products. Apple retained the one button mouse for accessibility reasons, and they also thought that users would be less confused.
In reality, how many people know how to use the full functionality of a mouse? It is a low percentage, though kids pick it up faster than adults. Try explaining how to use the right-click of a mouse to adults...you'd think you were covering planetary mechanics.
Regarding the thumb wheels...I use Logitech Revolution MX mice with both my Windows and Mac OS. Both work the same way regardless of the OS. Two button mice have been available for Mac's for years, it is just that Apple chose not to ship them.
