Hey everyone, I was wondering what the difference is between the higher-end MacBook Pro 13" and the entry model 15". I know the obvious differences, such as screen size, weight, and resolution, but I'm just not seeing why I would spend an extra $200 on the same notebook but with a bigger screen. I would like the 15" display, but I don't think I'm that desperate. If anyone knows of any internal differences that I'm just not seeing, please let me know. Thanks in advance for your help!
