Can't speak for the dual-core Atom 330 and Ion, but I had a netbook with the Atom N270 and GMA950 and it sucked. I couldn't play Hulu/Fancast on standard def, let alone HD (and it played fine on my Macbook and iMac, so I know its NOT my connection). I won't touch another net-anything anytime soon. (Not that my PowerBook does any better job, though, lol)
