I just ordered the 13" rMBP with 256 GB and 16GB RAM, after so many sleepless nights trying to decide between this and 15". I don't use my mac as often as I used to when I was in college. The most I do these days is tons of reports, and some Keynote Presentations. I mainly surf the web and watch movies and TV shows. When I was in college, I used to do 3D modeling and make blue prints. I tried to convince myself of the 15" because, who doesn't want to have the best thing? However, I tried to remain objective and realistic about my needs vs my wants. Having a 15" would be like having a expensive sports car in a city where you can't go past 30 due to heavy traffic. It would be underused. I am also nearly certain that the 15" upgrade will just be the addition of broadwell and force trackpad. I think Apple will wait for at least next year to bring a redesign to the Macbook Pro line (different colors, thiner, wireless charging, whatnot). I hope I can get the most out if this new MBP, and whenever I need to change again, it will be with a new redesign and not just internal upgrades. Although, I am still hanging with my iPhone 4S because I don't like the design of the iPhone 6. Hopefully that doesn't happen with a MBP redesign if it ever happens.
