I mean, I understand that you can upgrade the memory to 4GB by essentially purchasing a different price point MBA, but even on the specs page of Apple's site under configurations why does it have listed: "2GB of 1066MHz DDR3 SDRAM onboard (4GB maximum)" But for the flash storage, it lists 64GB and 128GB on separate columns with different model numbers? Essentially, if you cannot buy a 2GB MBA and upgrade it to 4GB later, then it doesn't have a maximum 4GB ram capacity. If I buy the 2GB MBA today, that's all it can be. Am I missing something? Even on Best Buy's site, they list the $999 MBA as "2GB DDR3 SDRAM For multitasking power, expandable to 4GB." If I can't buy that $999 model and expand it to 4GB, it's a false statement.... unless of course there's a way to switch it out. Food for thought.
