Even as a workstation - I already pointed out that Adobe and Serif won't port their apps to Linux. And that's one example of a professional use case. Think about the doctors, lawyers, technicians, sound engineers, video engineers, who all need to use some proprietary app that only works on Windows or Mac. Sure, if you're a programmer then you have access to everything you need on Fedora, but we are the least interesting group for the desktop, we are all power users and not the segment that matters.
