I bet path dependence has something to say about that. Try to force people to use Dvorak keyboards at work. Even though that layout is demonstrably better (more comfortable and easier to learn), people are already used to Qwerty, still have a Qwerty keyboard at home, and would generally resist change. Switching to GNU/Linux triggers similar problem: different GUI, still Windows at home, IT has to re-learn everything… Oh, and drivers. These aren't GNU/Linux's fault, but they still tend to underwhelm users. I, mean, seriously: ever tried to have your grandma use LibreOffice? The number one problem won't come from bugs. It won't even come from its inability to read such and such Microsoft Word document. It will come from her inability to "save as .doc" or "save as .pdf" so other people can read the document (and even if she could, it's still a hassle). Network effects are not LibreOffice's fault, but they still tend to underwhelm users.
