haha @ "etc,etc,"
It doesn't - my point was that single button mice are simpler for those that don't even use the 2nd mouse - those that still got over to the file bar to select cut/paste. These people, who never operate beyond the first mouse button. For them, extra buttons can be confusing. I mean, click, double click on one mouse button can be confusing for some, let alone 3buttons, and a wheel.
