Another distribution to try would be: http://moblin.org/ . It is a bit like Xandros but nicer and is a Fedora fork,
Moblin isn't really as of itself a distribution or a Fedora fork (although clearly it draws some material from Fedora, just as Fedora does from Debian, and Debian from Fedora and so on).
Moblin is a base upon which you can build netbook and small Linux distributions. That has several important differences from say Fedora eg that "It doesn't contain package X" is generally considered a feature not a bug ;) as the less dependancies in that base the better.
