APC Magazine has Xubuntu 6.10 on its January 2007 edition Cover DVD.
It works like the LiveCD (except it's a DVD), booting to the live environment with the Install icon on the desktop.
Xubuntu uses the Xfce desktop environment which is less resource intensive than Gnome (Ubuntu) and KDE (Kubuntu), making it a good choice for older/less-powerful hardware and thin-client networks. More information here.
