I'm going to be back in the market soon for a new laptop. Currently I have a white Macbook that's 4 years old and I'm looking to move up. I use my computer out in the field for photography. Macbook Pro is out because it's heavy and I'll also be getting an iMac at home for the heavy post processing stuff. I'm heavily considering the Macbook Air for its light weight. Problem is, I might experience regret of not having certain conveniences I now have with the entry level Macbook such as firewire port and 2 USB ports, not to mention a CD/DVD drive. Anyone later regretted getting the MacBook Air?
