I originally posted that tongue in cheek. The company I'm at, as well as many I know of, is running some 2003 and most are 2008. They are starting to move to 2012 and the windows admins are having a fit because there is no GUI and they can't just RDP into the system.
This has lead to "Your the Unix guy, you know command line stuff. Why don't you take over running these windows servers? They're just like Linux."
