Fanboy, Fan or Pitchman what's the difference?

Well, if you've been a avid reader of NanoGeekTech one thing may come to mind, damn this "MoFo" is a fanboy? But what really is a Fanboy? Are we all fanboies/girls at heart?

According to Wikipedia, a Fanboy is a term used to describe any individual who is devoted to a single subject in an emotional or fanatical manner, or to a single point of view within that subject, often to the point where it is considered an obsession.

A Pitchman is a man who makes a sales pitch: as a: one who sells merchandise on the streets or from a concession b: one who does radio or TV commercials, according to Merriam-Webster Online Dictionary

A Fan, aficionado, or supporter is someone who has an intense, occasionally overwhelming liking and enthusiasm for a sporting club, person (usually a celebrity), group of persons, company, product, work of art, idea, or trend. Fans of a particular thing or person constitute its fan base or fandom. They often show their enthusiasm by starting a fan club, holding fan conventions, creating fanzines, writing fan mail, or promoting the object of their interest and attention, sites Wikipedia.

If I prefer my Sony PS3 over a Nintendo Wii am I being a fanboy? "Maybe" But I also prefer Coke over Pepsi, NY Giants over the Redskins, Blue versus Yellow, a soft pillow versus a hard pillow, Summer versus Winter, money versus no money, Wordpress versus Blogspot, you get the point.

Fanboy is a term that is constantly spouted and dropped online for gamers who prefers a specific console or how passionately they defend their choice. One of the founding principle of any free society is the freedom of choice. We as gamers and people have a choice for the most part. What makes my choice better than yours? Nothing at all, it's all about perception.

So the bottom line I prefer my Sony PS3 over my Xbox 360 and a Craptendo Wii. Am I a fanboy, fan or pitchman?
