I had an accident with my laptop...when I tried to update some packages in Kubuntu, I managed to uninstall the entire KDE desktop (and firefox, thunderbird and everything else).
But luckily I could still boot into the console environment and could run apt-get install kde and lo and behold I was able to rebuild my machine with a few downloads.

And the cool thing is that I didn't lose a single document, e-mail or bookmark.
I wonder what would have happened if I'd accidentally uninstalled the Windows desktop...
