It also has an integrated 720p FaceTime HD webcam, and
a high-resolution LED-backlit 13.3" widescreen 2560x1600 (227 ppi) "Retina" display in
a case that weighs just less than 3.5 pounds (1.58 kg).

It does not have an internal optical drive.

Bluetooth 4.0,
two USB 3.0 ports,
two "Thunderbolt 2" ports,
