Kubuntu is a user friendly operating system based on KDE, the K Desktop Environment. With a predictable 6 month release cycle and part of the Ubuntu project, Kubuntu is the GNU/Linux distribution for everyone.
Kubuntu and Ubuntu are not meant to be seen as distinct projects; Kubuntu is part of the Ubuntu project, and they are both part of one development team that contributes to the whole. Kubuntu is Ubuntu with a different default setup, the Ubuntu CD contains only GNOME as a desktop environment; the Kubuntu CD contains only KDE, this is the primary difference.
