When creating a poll like this, it would be useful to specify the question in a bit more detail. Do you mean what is your primary OS or do you mean responders to upvote every OS that they use even only rarely? I use OS X and Fedora at home and Ubuntu, RedHat, AIX, Solaris and Windows at work, so I upvoted every option except for BSD (and, strictly speaking, OS X falls under BSD too).
