I'm curious why you choose Windows over OS X. I went from Windows, to Linux, to OS X. To me OS X is an alternative to Linux that just works. I still have a proper shell without resorting to virtualization and splitting systems.
The servers run Linux, so I develop on Linux. I also hate the OSX UI and its restrictive nature. I also play video games. I also do not want to pay out the nose for a Mac. There are tons of reasons.
