Hi there, I am going to get a new Macbook Pro in this next refresh, for sure. Now the question I need help answering is wheather or not to go with a 15" or 17" model. Let's put price aside, as most specs could be nearly identical. I am going to University in the Fall.. and I have always been a sucker for big screens. I would bring it to campus sometimes, but not all the time as I think it would be more of a distraction than a help. This will be my main computer. I also DJ on the side, so the 17" is helpful in that sense. The real question: Is how much of a weight difference is the 17" compared to the 15"... and is that laptop just too huge to bring around.. the 15" being more practical.. Any help is greatly appreciated! Thanks.
