Operating systems are fundamental to the world of computers, and yet many people have no idea what an OS is. For everyone else, it is a nearly religious form of expression. Seriously, there are very few people in between. You either have no idea or you have THE ONE idea. "OS zealots," as I like to call them, come in all shapes and sizes, but they have one very important trait in common with each other: they seem like normal people until the topic of computers is mentioned, at which point they become Frothing Messengers of Doom!! Quite scary, actually, and it might even be amusing at times. Those times when you are standing behind a 2-foot-thick wall of lead, for instance.
