At companies that let you decide for yourself (I've worked at 4), it's Mac and Linux. Windows is rare.. but there's usually one or two. Different IDEs. Just use whatever your more comfortable/efficient with. Admin use Windows, Mac is rare. I find it strange, in this day and age, being forced to use a single OS because "policy", especially when developing for an "open platform".
