Soon planning on ordering a macbook pro 13' Retina. Just wondering what I should get.. Through my school I can get 10% off. I could get these configurations: 16 GB RAM with 128 GB SSD (1404 euros.) 8 GB RAM with 256 GB SSD (1404 euros.) I'm not sure why I would need 16 GB RAM, but I want this laptop to last me atleast 5 years. I don't know how cramped it will get me, but I tend to use it for photoshop, producing, DJing and schoolwork... What do you think?
