An age old question. I'm a senior in high school and I need to get prepared for college. I'm definitely going to be buying an rMBP, but I'm not sure which. I'm currently using a 15" Y500 that weighs 6 lbs. With the laptop+backpack experiences I've had, this thing is a bother. Do you guys think a 15" rMBP would be suitable in terms of a college student in terms of size? I won't be carrying it very far, the school I'll be attending has a very small campus. Also, I realize the power to functionality ratio for a college student is less than what I'm buying. I'm sure I'd be able to get all my work done with an entry level MBA, but I like the power and performance, even if I don't necessarily need it. I know I probably won't need all the screen real estate to complete my work either, but, again, I just prefer it. So what do you guys think? Would the 15" be a good buy for me?
