i started out on macs with os 7, os 8 and then hopped over to windows 98/xp and even built a few windows systems myself. My main beef with windows was the annoying anti-virus stuff, having to restart the computer for lots of things, and rather than deal with anti-virus stuff, i'd reformat my HD every year or so, it just became a pain in the neck yet I was not going to switch to OS X until they adopted intel. As soon as intel macs came aboard, i hopped over. sure, it was fun fixing my own computer when i was in high school but in college, i just didn't have to mess around anymore and needed something that was much simpler to use. i still have a copy of windows on my mac and will use it from time to time. Even though i use OS X now about 95% of the time, i still see myself as a dual user and if windows becomes much better and OS X crashes and burns, well, i have no problem going back to windows. too many hard core windows techies are too stuck up to see if the other side is indeed better. i use the system that helps me get work done faster and right now, it's OS X.
