It's just people, innit? You get exactly the same stuff from windows users if you want to switch to mac. He's right, it's nothing to do with computers at all, it's just group mentality that's at play here. And you only get to hear the noisy ones - all the folk that are happy with their own choice of computer/OS and are happy with whatever anyone else wants to use will never get heard, because they're too busy getting on with it to bother saying anything.
