3 years old. Wow, how did they do all that in three years?

I really wouldn't bet my life on any OS. I would be happier if they ran on at the very least Trusted Debian. OpenBSD would be better, but I'd only trust my life to a machine that runs a completely custom OS built for one purpose that does one thing, and does it well. Thats why I'd trust the computers in a car before I trust any other sort of OS.

I really don't have a choice, though, so here's to hoping that people have enough sense to at least stop using Windows on mission critical systems.
