I believe it is also an option that had to be turned on in the OS, and that by default it still worked in one button mode.
The thing I like about the "one button" philosophy is that it meant that you never needed to use the second button to access something. There was always a menu or some other way, the right-click was just a shortcut (so I've heard). There were things in Windows and common applications that couldn't be accessed without a right click. It's also less confusing for new computer users.
Of course today, that's all basically gone. I'm sure some people use one button mice and are happy, but everyone I know ends up with a two button mouse or enabling the right-click function on the mighty mouse/trackpad. And it wouldn't surprise me if there were right-click only functions.
