This is interesting that arriving onsite with a Mac may get you on the network quicker. A lot of places I know consider Macs to be a black box, and generally "harder to support."

I personally feel I sort of graduated away from Windows in my career but ultimately if I was stuck with just about anything I feel like I could get some light programming, design, or admin work done, so it is weird to me that these debates go on. It's just a tool, tell me more about what you're doing.
