I might be a little late to the game here, but I thought I'd chime in anyways. I own and use both. Bought a 13" in 2010 right after high school because I wanted to save space (and money) and have used it for five years now. I've edited a ton of videos on it, but it's definitely tricky. There just isn't enough real estate. I bought a 21" monitor and that helped a lot. Utilize the big screen when I'm at my desk and the small when I'm traveling. This summer I upgraded to the 15" MacBook Pro, and, while it still feels small at times (I got used to using two 27" screens at work), it's much more condusive for Premiere. If you're going MacBook Pro, I definitely recommend spending the money for the larger model.
