My overall point is that Windows (in my experience) breaks at the slightest registry change or missing DLL or config file. Linux/Unix try to be as loosely coupled as possible, which means you can still run your in-memory gnuemacs (as in the article) even when your /bin directory (presumably with supporting binaries for emacs) gets wiped out. That kind of design takes a lot of thought and, as far as I know, doesn't hold true in DOS/Windows.
