FreeBSD-also a good operating system
I feel it better than linux
freeBSD is good, especially since Mac OS is based on it, ( i'm not entirely sure they still are, i heard something about a switch to a pure unix base... idk)
however, it doesn't have the support community offered by linux, and being so similiar to linux (though it has some unique features)... well idk..
Personally I haven't used FreeBSD my Dad has used Unix and even has a copy of Dell Unix. I am more familiar with RedHat based distros of Linux.
Just downloaded Sun Solaris so i'm gonna try that..
Of course after that i'll try FreeBSD.
Many people told me that it's a great system(including you).
