Linux isn't even a blip on the radar in the vast majority of shops. Having one in the building isn't the same as having a mixed shop. Until and unless the same variety and number of applications are available on Linux as on Windows, with the same or better user interface, Linux and all other flavors of UNIX will remain marginal outside the realm of servers. I've never understood the attraction of Linux specifically, anyway. Why not just run FreeBSD or something?
