What Movie Does Your Computer Run?

Last night a friend of mine asked me what the big differences among Windows, OS X, and Linux are. After talking my way through it for a while, I thought it would be best to use an analogy to describe it. So this one's for all of you out there who are new to computers: think of your operating system as a movie. The way I see it, the following movies relate to the type of movie stated;

Windows - The everyday, nothing-special, run-of-the-mill movie. These are usually the movies that fill up the box offices that everyone goes to see, but don't really care about too much. Think chick flick, teen comedy, horror, and action movies. Tons of people see them (just as tons of people are running Windows), but the don't get good reviews, and really aren't expected to. Some of them will get a lot of hype, but then let down everyone who goes to see them. Your friends see them, your family sees them, they keep the movie industry going, providing most of the income at the box office.
