I have the old 13" model and I love it. I'd not want a 15" model because I just find them oversized for my needs. Now, if they did a 13" model with the same resolution as the 15" I'd be delighted. However, if needed I use a little app that scales application windows. At first I just used it on my Dell Mini 9 (AKA my MacBook Mini), but it works just as well on the MacBook. Why Apple don't allow this sort of window scaling on the fly I really don't know. It works superbly and the OS is clearly capable of scaling windows whichever way you like (Expose is testament to the fact).
