About equal between Mac and PC and Linux a distant third. All devs use linux in deployment etc ofc, but I don't know many who use it as their primary dev laptop OS. Most seem to run it as a VM or something at most.
Yup, I was one of the legit Linux-using respondents, and confidently expected to be part of a small minority. When I saw the result I initially thought it must be a really specific demographic answering, but skullduggery seems more likely (even though I'd love for it to be true).
