The MacBook Air is a full-size 3 pound notebook encased in sleek, sturdy anodized aluminum. The 13.3-inch, widescreen LED backlit display is mercury- and arsenic-free. The keyboard is full-size and has backlit key illumination with a built-in ambient light sensor that automatically adjusts keyboard and display brightness for optimal visibility. MacBook Air also includes a built-in iSight camera and an oversized trackpad with multi-touch technology. The port hatch flips down to reveal (and closes to hide) a USB 2.0 port, headphone jack and a micro-DVI port. MacBook Air comes with 2GB of RAM built in, an 80GB hard drive and a 1.6GHz or 1.8GHz Intel Core 2 Duo processor (custom-built to fit within the compact dimensions of MacBook Air).
