Kieth,
Pretty much like everyone else has said, Mandriva, or Vista ;) If by "user friendly" you mean, great hardware detection, Mandriva is your answer. If you mean, easy to use, then Mandriva is your answer. If you mean greater user support forums, Ubuntu is your answer. I think the only problem Mandriva has is that its too damn good. I hardly ever have to ask any questions about it because everything just works. There are only three other distributions I can say that about; OpenSuse, PCLINUXOS(Mandriva based), and SimplyMepis(based on Ubuntu, havent tried the debian base yet.)
