I understand that the MBA isn't well-suited for video editing, and would hope most others reading this understand that as well. Of all the common tasks, video editting is probably the one that shouldn't be done on an ultraportable. Video editing demands a fast processor, lots of RAM, and large amounts of storage for efficient work, not to mention an easy way to get videos into the machine. If your main application is video editing, it seems rather odd to me that you're considering the MBAs. Apologies if this offends anyone, but it seems rather obvious to me. Outside of this application, pretty much everything else on the MBA seems to run extremely well with just 2GB of RAM.
