I'm heading off to college this fall and want to take a MBP with me! It sounds like the regular MBP won't be updated anymore, and the rMBP might me later. What's my best option? I don't think I care too much if I get retina or not but they tend to be more discounted in the refurbished apple store. I think I want refurbished to save money so I can get a better computer. How much difference is 4 vs 8 gigs of ram? I'm assuming 16 is overkill. How much difference is 512 mb vs 1 gig of Vram? I do want discrete graphics unless you all are going to say the integrated is just about as good, which I assume its not. I'm looking for any advice! Oh and I do want the 15" I think, but could do 13 if it came with dedicated graphics. EDIT: As for my intended use, I'm planning on being a computer engineer. Quite frankly I'm not sure what all that requires, but better to have too much power then not enough. If there are any specific questions I can answer to make answering my questions easier, ask away!
