Also, the dedicated 320M on the 13" makes it a real choice for me. I'm very happy about this update, but am kind of scratching my head as to why there's no 17" i7 and if the i7 in the 15" is a quad-core or not. Can't seem to find it.
NVM: I see the i7 17" is a selectable option, just not a preconfigured one.
