During my internship (summer 07) I was encouraged to use XP instead of Vista. Both my boss and mentor used it. Though this may be atypical, I don't think anyone cares what you run as long as you get your work done.

Don't know why you would want to use XP though, it seems pretty old and funky these days. And who really wants to check for spyware every day or two. I choose to use vista, but did a good deal of my coding in emacs, and kept ubuntu on my home machine.
