Huh, weird. The IT guys I work with don't just know Windows, when I joked about wanting a Linux instead they pointed out that we have software devs using Linux too. I'd need some reason to request it, but if I know the right people (and more particularly, what their favourite snacks are), I could probably get it approved.

(Doesn't actually help me, given I'm stuck using proprietary tools that I couldn't get to run with wine, but at least the option is there. And that's a big corp.)
