Just curious to see how many of us are open to alternative operating systems, how "religious" we are about those that we do use and so on.

I generally refer to Linux as GNU+Linux because on its own Linux is just the engine; all the other parts are provided by a huge slew of other people and I don't really care for Linus' attitude.

BSD is purer but less supported on the desktop.

Then there are other fringe ones but I'm sure we could get into that later.

If security is an issue to you, do you worry that the big ones (Windows and Mac OSX to a lesser degree) are targets for hackers.
