We first saw Thunderbolt on Apple's 2011 MacBooks, iMacs, and Mac Minis. In 2012, Apple added a second port to its top-end 15-inch MacBook Pro models with Retina displays. One of the reasons for Thunderbolt's existence is that it gives a single port the potential to serve multiple uses, and newer laptops have very little room on the side for ports.
