Ask HN: Any programmer/developer using Windows as their primary OS?

Yes

I'm using it at work and it's a pain. Don't go down that path unless you're writing windows applications. For anything else, use a real OS

At my new job, yes, but I solved the hideous problem by installing Babun, which is a package of a fairly good terminal emulator (mintty), cygwin, package manager, and my beloved zsh :-) I can use vim, grep, ls, find, sed, shell scripts, and much more. Like on Linux but without the possiblity to choose fluxbox as window manager.

I would suspect most are.. I doubt they read HN though
