I've just (about 6 hours ago) bought a Macbook Air 13" i7. I've been using Ubuntu with a 1920x1080 monitor so the screen size is a concern for me. However, the Macbook Air can easily power the external monitor so hopefully things should work out okay there. The reason I chose the Air over the Pro was cost vs performance vs size. As you started to get into the higher spec'd Pro's the cost started to get far too high for me. The Air is fast enough (especially with the i7 processor and SSD drive) that I'm comfortable using it as my main development machine and still has the benefit of being (almost) an ultra portable. (I'll be biking around with it a lot).
