I think that a lot of PC people who are very into computers and genuinely enjoy messing around with them end up projecting that interest on to other people. I used to do computer repairs, and I never understood why people used Macs, because the PC always seemed to just work so well for me. Then, I slowly lost interest in working on computers. After a few years, it all made sense. A lot of the little problems that I basically shrugged off because I *enjoyed* messing around with my computer, are big hassles to people who just look at the computer as a tool for getting things done, and even a necessary evil in a lot of ways. Once my mindset had switched to seeing a computer primarily as a tool, and not a toy, I found myself way more interested in an operating system that is more intuitive and user friendly, which OSX is for the *average user*.
Remember, if you are an IT guy, or someone who has been building PCs for years, you are NOT the average user. You are an advanced user, and you can't project YOUR values and interests onto people who are not interested in looking at or using a computer in the way YOU do.
