I've been shopping around for one of these (wife wants one for her b-day). Read a review at notebookreview.com and they gave it pretty low performance scores. I think 3d mark score was 90. Even still, it looks pretty nice.

Maybe the new Asus/MSI wind with the Intel Atom processor would be better?

Side note, I think the market for these things is going to go nuts -- Lenovo is releasing one in Oct. that looks real nice.
