I have always been of the opinion that only hipsters/startups program in Mac or Linux. It is my experience that major companies (HP, IBM, Intel, Microsoft and the like) provide Windows machines to developers.

Well, what do you feel about these results?

Which factors could be driving MacOS and Ubuntu numbers to be so similar between work and personal use? Is this an indication that I'm right and only freelancers/startups/hipsters use these? My reasoning behind this would be: The numbers refer to the same PC, meaning the developer bought it, so it is a personal PC, but they also use it for freelance work. Am I right on the money?

Ok, enough oxygen on the flames of the OS feud. Honestly, what do you think is driving these numbers?
