Sabayon is a Linux distribution described by its developers as "... a bleeding edge operating system that is both stable and reliable." It is based on Gentoo, a source-based (Linux) distribution. The latest edition, Sabayon 7 (GNOME 3, KDE and Xfce desktop editions), was released October 10 2011. Sabayon Core was released nine days after that (October 19 2011). The last Sabayon 7 editions, the Experimental Releases, featuring the LXDE, E17 and Awesome desktop environments, were released on November 9 2011. The GNOME edition has already been reviewed here. This review is of the KDE edition, which made my list of the top 6 KDE distributions for 2011.
