MacBook Air 13" Mid 2013

Released on June 10, 2013, this 13" MacBook Air looks much the same as its predecessor externally, but internally Apple made several improvements. A more efficient 1.3 GHz Intel "Core i5" processor results in improved battery life and faster graphics. Other features include 802.11ac Wi-Fi and Bluetooth 4.0 connectivity, a "Thunderbolt" port, an SD card slot, and two USB 3.0 ports.
