Okay so power-wise aside, which size would be better for college? I don't need the extra horsepower that comes with the 15" I'm looking strictly in terms of the screen size and portability of it. I know that the 13" would be more portable but seeing that I would be on the laptop for hours on end sometimes I think that the bigger screen size would be better. So if anyone that has actually been to or is going to college can give their input on each one that would be great. I'm currently leaning slightly more towards the 13" for the portability but don't wanna regret not going for the bigger screen later on. Just some questions I had in mind were like: Will the 15" be too bulky to move around? Has anyone with a 13" ever wished they had the extra screen size? Is the weight difference a noticeable hindrance? Thanks guys!
