A factor that can be overlooked is the screen resolution. Normally the 13" screens only go to 1366x768 which can feel like reduction in screen real estate, especially if you have your IDE set up with side panels etc. However I've found with a full 1920x1080 screen if you handle the smaller text everything lays out exactly as it would on your desktop monitor so it doesn't feel as squashed. Best of all nothing changes position when you dock back at your desk. Given the resolution of the 13" MacBook Air Retina is 2304x1440 as long as you can get the font the right size you'll have plenty of screen space.
