To make the best Linux ever, you need to download Ubuntu 9.1 and Kubuntu 9.1 Live CDs. Install Ubuntu 9.1 onto the hard drive. Go into the terminal and type "sudo apt-get install kubuntu-desktop".
Normally, I was too lazy to put into that one line so I kept downloading RPM based Fedora and OpenSuse, because I'm only human.
That other distro I'm using since 2003. It's American.
