I know the new MBP's are capable of supporting 16GB of RAM, which is what I would like to upgrade to. It's been 2 years since I got a new MBP, and this new retina display one will take over my mid-2010 15" MBP. However, like the MacBook Air, in which you cant upgrade the RAM yourself, is the RAM in the 2012 MBP something that only Apple can do for you, like the MacBook Air, or can you purchase your own RAM sticks and stick them in yourself, like all previous model MBP's? I watched the video explaining how Apple designed the new MBP, and saw the internals of the computer itself, but couldn't find for the life of me where the RAM slots were. I'm curious, as this new machine is worth quite a bit of money and I would like to save as much as I can wherever I can. I'd like to know before I should fork out the extra $200 for the RAM through Apple. Thanks in advance.
