Any ubuntu users out there?

Just curious if CorD types are using the Ubuntu Linux distribution and if you are promoting it. Seems like a good fit, certainly for the techie types here and open source advocates, but also increasingly good for users with no experience beyond Windows or Mac. I bought a Dell xps with ubuntu pre-installed and after a little initial apprehension am finding it a real pleasure to work with. I'm new to Linux, so I'm a good test case of the usability of Ubuntu for newbies. If you want to check it out you can download the software, burn a CD and run it on your PC without installing it. (Haven't tried that, mine was preinstalled.)
