I know Ubuntu and Kubuntu topped the charts this year, knocking Redhat, mandrake and Suse off the top of the block at Distro watch. A real nice and simple Distro, that just seems to work. Plus! You can get multiple CDs free-o-charge and pass them out willy, nilly. It may not have been the break out year folks thought, I think that will come in 2006 when Vista launches and folks see what MS has in store for them. The bells and whistles that Vista promised (gone) and the carcass they are trying to foist off on the end user, will drive alot of folks to linux, or at least make them realize that XP might be as good as it gets for a long, long time.
