[2] Y Combinator is (we hope) visited mostly by hackers. The proportions of OSes are: Windows 66.4%, Macintosh 18.8%, Linux 11.4%, and FreeBSD 1.5%. The Mac number is a big change from what it would have been five years ago.
I'm interested to know what the proportions of OSes are today.
Well, I would have answered Linux on that poll, because I use it as my primary work environment. But I almost exclusively use Windows for web browsing. Maybe I'm atypical though.
I just spent the weekend at a hack day (http://leedshack.com) in the UK, with over 100 hackers. I barely saw any windows machines, almost everyone had a Mac.
I've noticed that the percentage of Macs in the same group is higher at events than it is online or inside companies.
One could speculate about the reasons, but I do know that seeing hackers I respect with pretty shiny Apple laptops is what triggered me to buy my first Mac back in 2002.
