Kubuntu Gutsy (Canllaith.org)

Think you miss the point of Ubuntu and it's flavours.

The Kubuntu or Ubuntu or Xubuntu for that matter allows users to get their favourite desktop
environment off the bat, with a bunch of apps/utils for their environment.

Sure, you can install say GTK libs for those KDE users and KDElibs for those Gnome users...
and most power users do..

However for Johnny Learner, it's an easy way to get their desired Desktop environment in a
bootable/installable CD.

Once installed.. just use apt/synaptic to install any of the other bits and pieces you like
(such as the alternative libraries).
