Hi, I'm looking to buy a 13" retina Macbook Pro, but I'm limited on my budget. I'm debating between a refurb October 2012 model or the new one announced today. The new one is about $230 extra with taxes compared to the old one. These are both base models. From what I gather, the new ones have 4GB less ram, but a slightly better processor and a lot better graphics? I don't plan on gaming, but I want a computer that is snappy and runs smooth. What do you guys think is the better deal? Will I see a huge jump in performance going with the one released today or should I save my money and go with the October release model? Thanks!
