I think a guy (or gal) should use whatever computer and OS floats their boat. I haven't watched the video yet, but the only Mac people that bother me are the ones who talk about all the great things a Mac can do, but they can't make it do any of those great things.
For instance when I'm told how a, "Mac is Unix" and I ask the individual to pop open a window and list a directory, they give me a blank stare and begin to drool a little bit. If you can't use the BSD, then your Mac is not Unix. Also when they, with an air of superiority, throw out terms like "Time Machine" as if Apple invented backup prgs. It's a nifty enough backup prg, but there are nifty backup programs for every OS.
If you like and enjoy your Mac, more power to you. When you turn owning your Mac into the South Park Prius episode, you just annoy everyone and give other Mac users a bad name. The personality type isn't indicative of Mac users, it's more that the personality type is drawn to Macs more than to other computers, and somewhat skews the Mac demographic.
