Externally, the 2013 MacBook Air is nearly identical to its predecessor, including the model number (A1466).

The right side ports haven't changed a bit, with the new MacBook sporting the same lineup of SD card reader, USB 3.0, and Thunderbolt port.

A 180° rotation gives us a glimpse of the only noticeable change to the outer case: two ports for the dual microphones along the left side.
