Having design-OCD and wondering for some time why the hinge (in a very un-Apple-esque way) was protruding from the screen I looked at it from the side and find out it's now a triangular shape that doesn't cover the vents anymore. This new hinge is an awesome design change. It's the attention to detail and small innovations that make me so happy. I absolutely love the new "through body" ventilation system. I wonder if this technique will be used on the other MacBooks and iPads. I'm passing on the 15 inch because I like the 13 and 11 sizes more.
