In that case, I would look long and hard at the
13" MBA with 128GB SSD:
$1399 including the $100 upgrade to 4GB of RAM (which can only be done when you buy the MBA).
In fact, if the MBA had one of the new Sandy Bridge processors and Thunderbolt port, I would've opted for that instead of the 13" MBP I just bought. Apple never makes these decisions easy, do they?
