I work in TV and film and use all three operating systems daily! I go where apps go. OS itself rarely matters since all I usually see is an application itself. Linux and MacOS (well, basically anything GNU-based) offers a lot more flexibility and automation. Not that Windows cannot do it, but that my colleagues and myself are more used to ye olde *nix. Windows, on the other hand, just works! Sorry, couldn't resist.
I use MacOS, these days, mostly for writing (occasional coding) and on the go editing on macbook. Nice example of what you've mentioned is Fade In Pro http://www.fadeinpro.com/ which filled vacuum left by impotent Final Draft (this is changing now with FD 10 slightly). It's just GREAT that you can use the same application in all three environments. In case of Fade In Pro you don't even have to buy separate licenses.
