If you are one of the few who brought the tidy new Eee PC from Asus (lucky buggers!) then you need not stick with Xandros for long. A new project is currently underway to provide GNU/Debian Linux as an alternative Free OS for Asus Eee PC.
For now you can resort to apt-pinning to install Debian packages on Eee PC. Hang around for more updates on debian-eeepc project.
