I'm a longtime Mac user, but also administer a network of a dozen or so WinXp machines, along with a Mac mini, a couple PowerMacs and a couple Powerbooks. I honestly think the most ridiculous thing Apple does is sell their one-button mice. I can't stand 'em. Won't use 'em. Bad ergonomics, you can only grip them one way and still click, and no right-click contextual menus. All that is before you get to the scroll wheel - the very best innovation in user interface in decades. So, Mac fanboi that I am, the very first thing I do when I set up a new Mac is attach a Microsoft Intellimouse Explorer to it.
