The MacBook Air also features a built-in iSight webcam, a full sized MacBook-style black keyboard, 802.11n-based wireless networking support, Bluetooth 2.1 + EDR, and a 1.8-inch hard disk drive with 80GB of space. A 64GB solid-state disk (SSD) drive is an option. The laptop is powered by an Intel Core 2 Duo chip running at 1.6GHz, with 1.8GHz available as an option and includes 2GB RAM.
