Xandros is another option. I got it up and running on my T42 in a little over an hour. It was very easy to install and use and the interface seemed 'snappier' than Ubuntu with Gnome.
Search for Xandros in the 'Hot Deals' forum for how to get the OS and the .pdf manual. My main gripe about Xandros is if you want the latest software you have to pay for it.
