Unix command line driven tools are a big part of my work and the native OS unix does everything I need it do. It seems a lot of people became committed to Linux coming from Windows with no unix system under the hood. I suspect if Windows had been unix based like Mac OS, Linux would not have become quite so popular. I'm sure avid Linux users will disagree, but for me the unix model command line interaction is what matters. Go easy, I'm not trying to make an argument for one unix over another. Just arguing that the need for a capable unix is already met by the native OS.
