The only time this whole "war" gets to me is when I'm minding my business using my powerbook and some smart a$$ walks up to me and starts with the whole Mac/PC nonsense. In an airport once I had to tell the guy to stop trolling because he was not on the internet and I was in particularly ornery  mood and I was going to hurt him. (layovers, delays, etc.) There was no need for him to start with me. I was sitting down charging my mac finishing up a movie that I started on a previous flight. (With earplugs!)

The sad thing is that any discussion with a PC zealot ends up reinforcing the, "arrogance" myth. I'm a nice guy, usually, and if someone asks me a non-loaded question I am happy to oblige. Most of the time it starts with, why did you waste your money on that? You could have..... Thats not nice and will not elicit a nice response.
I have never walked up to someone using a Dell or HP and bothered them. Never. I don't understand the compulsion to bother people with Macs. (Usually people just hover around and then decide to leave me alone. I'm not a very inviting looking person. Just every now and then someone gets a bug up their a$$ and deices to ruin my day)

I usually never take part in these threads because they are pointless. Everyone just gets pissed off and walks away with greater ill will toward the other camp.

A computer says absolutely nothing about a person and judging based on computer of choice is foolish. My friends have very similar personalities and they all use different platforms. Some Mac and some prefer PC. Some have a Craftsman drill at home others have Dewalt. Who cares.
