Interesting observation, now that I work in a mostly-Mac office... (I have the only PC) All of the Mac users have PC's at home in addition to their Macs, which they use almost exclusively for browsing the web. The reasons for this became especially clear when I rediscovered just how unbelievably slow web browsing is on the Mac.
Mac users, let me know: do you use a PC to browse? Are you aware how much slower Mac browsers are on comparable hardware?
And it's not a religious issue, I like Macs plenty. It's just amazing that they've lagged so far behind in such a critical area.
