NVidia is trying to rush the gate before Intel is all. Price needs to mature a bit first... this is early-adopter stuff and I wouldn't buy it.
I can accept the DX9 sacrifice, this is a NETBOOK after all. If you want to frag enemies in FPS games like Crysis and such, get a regular laptop for that... this would be ideal for older titles (GTA III/Vice City/San Andreas, Sim City 3, etc.)
And this would rock for MMORPG players who typically don't need high end hardware to be able to play, just enough to crank out 20-30 fps in a small cheap package is enough to put a smile on their face. (My netbook is close, got the Gateway LT3103u two weeks ago... average FPS is 12-15, but at least I can play.) But the price is still a bit too steep for the promise: cut it another level to $450 or below, and you might have something.
