I think these are pretty rare. They are the successors to the UL30vt. IMO, they are pricey for the spec (the 310M is kinda entry-level graphics). If you don't mind downgrading the CPU a little (even then, some CULV match the i3 in some benches), you'll have the Acer Timeline 3810TZG / Acer Travelmate 8371 (with HD4330), that'll do 90% of that asus at 1/2 the cost. Those two acers are really hard to pass given their price / performance / feature / mobility potential.
