Just noticed these while browsing the latest 15'' MBPs in an Apple Store. Apparently the fans no longer blow from the hinge into the screen, as on my 2011 model. According to the employee I spoke to this was causing damage to screens. He also informed me that the latest MBPs are fanless, which sounds implausible. Can someone confirm? Also, how is the new venting design working out for users putting these models under heavy loads (eg. that infernally-taxing pastime called, "watching a Flash Player/Silverlight-based video")? Do you have to be more aware of the surface you rest your MBP on?
