Got my Macbook Pro Retina about a week ago. Walked into a Best Buy and they told me they didn't have any so I walked around the store and 5 minutes later the man told me two just came off the truck. Got the first one. Love it so far. But I'm curious, how is Mountain Lion supposed to improve the user experience on this new machine? What features will be added or improved specifically for the rMBP? Thanks for any replies in advance.
