The reason that it seems that two-buttoned mice are better is that we are technically proficient people able to use it to our advantage. Looking from the point of view of a beginner to computing, which most people here on this forum are not, I'm sure that one button will be much easier. I know that I have taught people that had continuous problems remembering which button did what, and remembering which to use for what. A one button mouse should be enough for most people anyways, since most of the commands can either be accessed from the menu bar or the keyboard as well. Besides, even if Apple did ship a stock two-button/scroll wheel mouse, I'm sure that most of the people here would still be complaining (about not having 50 buttons like the fancier ones). Bottom line if you want one get one yourself, if not you can use the stock one just fine.
