content: Been using Linux/Unix, Mac and Windows for over 30 years (yes, I'm an old fart)... I, like many other geeks out there, can happily and easily run whatever OS I want. Linux is my primary OS and lives happily on my laptop. I've got Windows however on my desktop for development. I prefer Linux for most things, but the world runs Windows and if you're developing for Windows users, guess what you run?   For example, I do 3dVR (Oculus Rift/etc) development. The Linux side is and always will be woefully behind. End of story. I'm stuck with Windows whether I like it or not. There are plenty of other examples. If you're in a design shop... you run Mac. It's just how it is. Swim upstream if you like.
