Hello! I have been on macrumors a lot, but just created and account to ask for some advice/input for a purchase. My mid 2008 black MacBook seems to be on its last leg and I'm looking to upgrade. I was looking at the 13" retina MacBook Pro (w/ 256GB SSD), but now the 15" is on sale at best buy for $1,750, plus I have a $100 education discount coupon. Is it worth upgrading just for the larger screen? I don't "need" the extra processing power, ram, etc... But do you think it's worth it and will it be more future-proof than the 13"? I don't do anything major on my laptop besides using the web, some word processing, streaming videos, etc. is it worth the upgrade for just the larger screen, more ram, and quad core processor? If I don't buy now then I'll probably wait for a 13" with sky lake to come out.
