Computers suck, in general. I have a hard time seeing an attempt to leverage blame on Windows or Linux as anything but an excuse to start a flame war.
My gripe with Windows is usually not related to the operating system itself, but rather the direction it's headed as a product. And I also don't like that when people say that Linux is so tinker-y, compared to Windows, which "just works". A system that "just works", in my experience, is a system that the user is used to. Familiarity makes the issues seem trivial, and the unfamiliar issues seem insurmountable, which hardly results in a fair comparison.
I don’t think it really matters if windows bugs exist, but how often they occur and impact use of the tool.
The major difference for me is that Linux problems are always theoretically operator-fixable i.e. the information needed to fix your problem is available to you, even if you're not technical enough to understand it. The means to fix Windows problems are frequently not accessible at all, anywhere.
While I've had plenty of Linux evenings, I've had stuff broken on Windows that stretched into weeks until I finally gave up and reinstalled.
