Our sister blog jkOnTheRun has a
good story about eeebuntu, a new Ubuntu Linux distribution that is specifically customized for
Asus' popular Eee PC laptops. You can go with the snazzy Compiz Fusion enabled GNOME version or go plain-vanilla with the Ubuntu Netbook Remix packages. You can
get the distro here, and you can
quickly return to the Eee PC's normal Xandros Linux if you want. Quite a bit of open source software comes with eeebuntu, including Working WiFi, OpenOffice, Pidgin, Skype, Firefox 3.0.1, and the VLC media player. Those little Eee PCs are a steal at around $350, by the way. I have one.
