Almost all developers I personally know use a Mac. I know a few that use Linux on occasion. I personally know of no developers that actively use Windows for writing code. However, I'd argue that using the OS you use for development is less important than understanding what is happening when you run software on any platform. Ultimately you'll need to deploy software somewhere, and you will need to understand what is happening when the software has a problem. You often won't have a choice about the operating system on which your software is deployed, and you will still be expected to understand the OS well enough to work with it. I say focus on understanding what is happening to the extent that you can. Always be curious. Always learn. Always strive to learn what question you should be asking to get the answers you seek. And when the trusted advisors & Google fail to answer your questions, that's where the real adventures begin. And, if you'd like to make money, don't forget make find a way to get paid.
