I have been intrigued with FreeBSD since I heard of it many years ago. (after some experience with Linux) I actually preferred it over Linux.
The choice to go with Linux as a host to my servers had more to do with compatibility for a rich multitasking environment. In fact, I preferred the FreeBSD web server environment. I would have happily used it for my “production” web server (this server) if not for some pretty castrating compatibility issues.
Needless to say, FreeBSD has always held a place in my heart.
