Hi, since this is kind of my very own first Mac, (I've been using my dad's 2009 MBP), which one should I get? The 13" rMBP 256GB with 8GB ram or the 128GB with 4GB ram? I will be going to the university as a computer science student, plus I want this computer to last about 3 years before upgrading to a new macbook. My usage is of course programming, some photoshopping, web surfing, etc. I might install some games, but I can store it in my external hard drive. I might be running visual studio through parallel if I need to use visual basic. If there is no point of getting the 8GB, then it would of course cut the cost and I can use the money to buy some other thing without asking extra money from my parents.
