About ten or 15 yrs ago there was an excellent article by Italo Calvino in either Harper's or The Atlantic in which he compared the Mac vs. Windows thing to religion. He made a case for the Mac side as Catholic and the Windows side as Protestant.
Aside from the fact that I'm a card-carrying atheist and it smarted a tiny bit being thought of as Catholic, it was a beautiful article.
Anyway, it does remind one of fundamentalism. Tiresome, isn't it?
