There is really no point in having a 13" MBP and MBA.. Sell the MBP for the Air or pass.

once you own an Air, you'll be spoiled for life.
sounds like it's ideal for your needs
buy a refurb unit as has been suggested - with an SSD.
(2.13ghz would be my pick)
mine still flies.
(and I do watch movies on it with no issues)
when the Air is updated - which is looking like early 2011 at least - you then have a choice to upgrade or stay with what you have.
unless it's a blindingly sweet and powerful update I see no need to part with mine at least until the 3 year warranty has concluded.
there
will be another Air despite what the nay-sayers are saying.
I'd say Apple are waiting for the right blend of components to become available, and as I mentioned in another thread, recent acquisition of Liquidmetal Technologies will surely be a significant factor going forward for all Apple 'lightweight' devices - including the Air.
all this bleating about being out of date technology, etc, etc, belies the fact that many Mac users are still functioning more than adequately with C2Duo processors in MacBook Pro's etc and only a minority have to have the latest and greatest.
with the advances Apple have made in the Mac OS, Snow Leopard functions just fine on these 'old' and 'antiquated' machines.
(howls of protest will follow this comment, I'm sure)
