Go with Xandros. It's an excellent distro I know I have it everything is soo easy. There is no need to install the ATI or nVidia drivers because it does it for you It is also KDE is extreamly organized, it's easy to find programs/files (looks like windows) you also don't have multipul of the same program(eg office) network was too easy all you have to do is...nothing ;D ;D it also come with CodeWeavers(deluxe edition) and RealONE(don't bother installing). It's also very fast IMO.
i'm very sleepy now so any mistakes just ingore it.
EDIT:it also has flash and java installed so any java apps (eg LimeWire) work.
