Making the Air come standard with 2gig RAM shows that it's going to really need it to run the OS X and apps at a 1.6gig processor.

I admire your conclusions' jumping ability =O.o= But I'm running OS X and many apps including photoshop, synergy and three different browsers on a 1 GHz PowerPC G4 (with only a single core, obviously), with only 1 GB of ram, and doing fine.
