Funny I consider myself agnostic but I'm usually seen as a "young developer" despite having been doing programming as a hobby for at least 10 years now. I guess professional experience is worth more to be fair.

I'm in the camp that uses Windows, Linux and Mac. Whatever laptop is nearest to me and gets whatever task done the quickest is the one I'll use, and these days it's my Surface Book 2 which has replaced even my iPad from being my media consumption device.
