If there was a chassis re-design i would like too see if they will trim down the bezels around the screen.
the MBP can have a thin bezel why not the air? surely that would further help to differentiate it from the macbook. its achievable without sacrificing much.
I admit that isn't so apparent a problem in person, but seeing apple's pictures of it makes the bezel seem inconceivably huge for a 'ultaportable'
Practically i don't really think it needs to be faster (some would even argue going slower would be beneficial), but smaller, cooler processors will be appreciated along with more ram. SSDs are rapidly decreasing in price maybe in the next 6 months 128 gigs will become the
standard drive, with 256/512 gig drives for higher end model.
GPU wise i don't think much change is needed, of course the updated chipset with the x4500 would be nice, depends on the heat dissipation, gaming would really push the thermal envelope that the air is capable of...
And a price drop is always appreciated
