Oh Sorry Captain Picard. Didn't know about MRoogle....Guess I'm a noobie for a reason right?
Don't worry about it. People like to complain about people starting new threads. It's really only annoying when someone will start four or five threads and ask the same question in different sections of MR.
I think it's fair to assume the RAM could be updated in any computer, as Apple really screwed people over by soldering it to the board and not offering the option to upgrade. The problem with the MBA is it's all crammed into a tight space, so there's no room to have a RAM tray with two connectors. I think the updated MBA will have either 4GB RAM or two RAM slots that support up to 8GB RAM.
In the end, the only real update available to the MBA right now is to a larger SSD. Runcore makes the SSD that performs much better than the stock SSD. For now, we are all stuck with 2GB of RAM if we have to use an MBA.
