I've done something similar. I have a 13" Macbook Air and found that I can focus better when I'm staring at just one screen. This sandboxes my attention: do one thing at a time, finish it, and move on to the next thing. Most of the time my second monitor was used for email and Twitter, which was a constant distraction.
