This is my 3rd UNIX after OpenSolaris 2009.06 and Solaris 11. It runs the KDE 4.5.5 and Gnome 2.32 desktop environments. It has a long uptime is an indication that no crashes have occurred and no kernel updates have been deemed needed. Unlike Solaris 11, the PC-BSD DVD gives you LibreOffice, The Gimp, Empanthy IM, all the KDE and Gnome programs. I test it on the PC that only takes Ubuntu Linux & Linux Mint. It does feel like a Linux, yet without Crossover Linux Pro. I am searching for free Bordeaux somewhere. I need bordeaux for VLC & Winamp. Kubuntu kicks PC-BSD's butt in all benchmarks! That meaning a less secure Linux would be better. No wonder few go with UNIX.
