There's a torrent floating around out there of the Dell restore image for the version of Ubuntu they ship with it, and I know that Ubuntu 8.10 will work as well.
I'm in the process of getting other, more strange versions of Linux working on it - but that's my obsession, not yours!
Beyond tinkering with Linux, just have fun with it. It's a great little machine and I don't know how I've done without it all this time. Congrats, and keep us posted about how things go!
