Nope, I like Windows XP, never had any problems with it and it runs everything I need it to.
I could mess around with Linux all day long but I've got other things I would rather spend my time on, so I don't. You have to understand that while running a better system is really important to you, most of us just want our computer to work when we turn it on and since most pre-made computers come with Windows, well there you go. Also, most people in my experience aren't willing to learn the nuances of more than one or two operating systems. For them Windows was hard enough, mac on top of that make two, why would they bother with Linux? I'm not trying to diss Linux or anything like that but saying "mabey comfortable but they really really don't like it." is a huge stretch
