Okay, lets get this straight: a PC luser is someone who blindly uses Windows and resents any other platform/OS other than his own. They are usually weak-willed with large egos and M$ has taken perfect advantage of this. Not everyone who uses a PC is a PC luser. Windows-users aren't necessarily PC lusers either, just as long as they realize how crummy their OS is. As long as they don't support M$ in any way, Linux (and all those other obscure OSs) people are fine by me. A Windoid is essentially the same thing as a PC luser.

Also, I think everyone knows full well the use of the letters PC. If you really want to nitpick, I suppose Macs are PCs as well (hell, it says PowerPC on the side of my Performa) but PC is commonly used in reference to non-Mac computers primarily designed to run Windows. I think you know this already.

I hope that clears it up.
