Pretty excited today as I am now the keeper of a MacBook Pro Retina. Though it does not exactly belong to me (company machine) - I am it's keeper. Super excited and learning my way around. I actually haven't used Mac OS in a while. Kind of weird to be (what I would consider) a iOS pro, and a OSX novice. Anyways - its 15", 3.3Ghz (turbo Boost to 3.6GHz) - 16GB RAM - 512GB Flash HD!
