Well, I like to think that I took pretty good care of my computer back when I was still using XP and it still gave me lots of trouble on a regular basis, which lead to doing format c: on a yearly basis just to get things running smoothly again. Sure, virus/trojan scanners are nice and all. I'd get some for the Mac too if only there was someone out there that actually wrote viruses for OSX. About the mouse: The bundled 1-button mouse certainly is awkward, which is why I got me a 5-button mouse. (All the buttons and the scroll wheel work both in WoW and in OSX) I find it interesting that more and more home users are switching to Macs. Wasn't really that many years ago, when Macs were mostly used by professionals in the graphic industry where the Mac was somewhat undeniably considered the supreme system. Today, the tables have seemed to turn, since the new versions of the Adobe product families for instance, might actually perform better on a Windows platform. So the Macs are becomming more and more of an all purpose system instead of a workhorse for hardcore graphic designers.
