Hey Folks, I noticed some activity on the linux threads and I wanted to start this one for users of linux and unix here are my favorites: Debian - Simply the best to me, I like the package manager Apt, and I just enjoy the robustness of the core architecture. Most popular distros are built upon debian. Studio64 - A distro created for multimedia users, it is an awesome distro and to me is better than Ubuntu Studio because it contains less bloatware. Red Hat Enterprise - I am a Systems admin and I really enjoy the stability of our RHEL boxes, they are gangsta. Solaris - What can I say, simply the best Unix platform. Distros and Unix' versions that I am not fond of: FreeBSD - Are you serious? Zeus - Come on man, this thing is not great SUSE Desktop - This thing is Cheesy, but Samba works out of the box and LAMP does for Enterprise version.
