Please note Ubuntu/Kubuntu "Dapper Drake" is not yet a final product and the available previews do not reflect the quality of the final product. This quick review is not meant to divide Ubuntu and Kubuntu into separate distros. They are almost identical to each other, except the default desktop for Ubuntu is Gnome, whereas KDE is Kubuntu's default desktop.

"I hope I am not making a mistake." Those were my thoughts as I decided to upgrade my Ubuntu system (5.10 Breezy Badger) to the still under construction 6.06 (Dapper Drake Beta)

At the time I was not sure if I should do a clean installation (download a +-650MB ISO, format etc) or edit my sources.list and do an apt-get distro-upgrade.
