I'm a fulltime developer, and a macbook air 13" is my main machine. I love it, and wouldn't trade it for anything. The battery life is better than I've ever had before (4-5 hours in real world scenarios), and the portability can't be beat. At the same time, it's not too small to do real work on. That being said, I do hook it up to a 30" dell monitor & mouse and keyboard when I'm not out and about.
