content: This. 1000x this. I worked at a small for-profit college. I used Linux at work for years, dealing with minor headaches and checking for document compatibility. Everything worked fine. Nobody cared. Everyone else just kept using Windows. My next job? I got hired because I could teach Windows programming to students who were hired for Windows projects on Windows computers. One of my highest-IQ students was a hardcore Linux fan, even did free tech support for the Ubuntu forums. He came back to school to get a 2-year degree programming Windows because he wasn't making money. If your job lets you use Linux, if you make money using Linux, good for you! But for many of us, our ability to feed our family depends on Windows.
