Google Acer 1810, it's a netbook sized laptop with a ULV c2s (there is also a 1810TZ coming out which is ULV c2d) which will probably beat the **** out of the Atom for processing power.
As for graphics, they ship with Intel 4500HD -

Also, the Acer has upgradability. I'm planning on picking one up when I'm in the states at Christmas, dumping 4Gb of RAM in there and a 320Gb WD Scorp Black.
