It doesn't have officially-supported status (yet - Mark has expressed interest), but the one I'm currently keeping a close eye on is Lubuntu - Ubuntu with an LXDE desktop. LXDE is the first environment I've found that manages to be both lightweight *and* easily understandable for relatively new users. Conveniently enough, as of Ubuntu 9.10 all you need to do to get it is install a minimal Ubuntu system (use the alternate CD), and 'apt-get install lubuntu-desktop' for a selection of default packages, or pick and choose your own. The 10.04 release should be very solid from the looks of it. A note about support / repositories: Remember that Ubuntu does have LTS (Long Term Support) versions, with the desktop side being supported for 3 years and the underlying and server stuff for 5 years. Even after the support period ends, you can still find repositories for EOL versions at old-releases.ubuntu.com - Tony Yarusso
