I am looking into getting a new Macbook Pro. What are everyone's thoughts on the 2012 vs the Retina? Is the retina screen worth the price to buy that over a refurbished 2012 Macbook pro? It's a pretty big price difference. I like being able to upgrade the ram and hard drive on the 2012 and being able to take out the CD drive for another storage drive. Also what about the CPU? Either in the 2012 or the new Retina, is it worth the extra money to get the higher CPU? Also what about the graphics cards?
