I am a college student and am looking to buy one of the new MBPs. I would like the 15" one but I don't know if it going to be very portable. And so I am leaning towards the 13" one. The main thing is that I like to watch movies and that is the only thing that will be better on the 15". I know most of you will say buy the 13" and then get a monitor but I don't like to sit on a computer chair and watch movies (I prefer my bed). However, #1 priority is portability so if the 15" is too much to lug around, I wouldn't mind settling for the 13". People who own 15" and 13" (and hopefully those who have owned both) want to chime in with their opinions?
