An other way, it is when, I buy the MacBook 13.3 and then a extern monitor. Then I can use the MacBook for mobile things and when I want to work with post production programs then I can connect both and then I can work on a bigger monitor.I would go with the largest screen size you can afford, if theres a 17 or 19 I personally would go with one of those or larger if thats possible. I have been using a 22" monitor for the past five years now and using anything smaller feels so cramped and quite annoying to me now.
