Interestingly, I've seen a small group of Windows fanbois arise within the last couple of years. Very much like the Apple fanbois; just as irrational and quick to take offense at any criticism of MS and Windows.
But I agree with you that most people I know also tolerate windows. Some are even happy with it because they can do things with a computer that has windows.
That was until Windows 8 came out. I was surprised by the amount of hate windows 8 received, and it was well deserved IMHO. But then I was also surprised by the few people who didn't hate Windows 8, some even liked it. The fanbois.
