So I'm actually beginning to think that the MBA is the right laptop for most of my work. I have a 27" iMac that I use for serious Lightroom/Photoshop work (that's really the most processor-intensive work I do), and when I'm on the road the Air would be used primarily for MS Office, and managing some photo shoots on the road. I'm thinking that the 128GB SSD would probably be ample for my needs, and I would add a USB 3 or TB external drive for storing photos (my nikon D700 makes some RAWs that are anything but tiny). Otherwise I really wouldn't need to install much on the MBA--maybe a game here and there, but more Angry Birds and less Diablo. Sticking with the 128 SSD would obviously save some cash for a nice external drive and the 8GB RAM upgrade, so that would be nice. Anyone out there using an MBA with similar needs? I guess I could splurge and get the 256 anyway but if 128 does the trick I might as well save the cash.
