Thin-Ovation. Introducing: MacBook Air, the thinnest Notebook in the world.
At 0.16 inch at its thinnest point, just 0.76 inch at its thickest point, and a mere 3.0 pounds, MacBook Air is so compact and light that you can take it everywhere. But unlike other ultraportable designs, it doesn't compromise on features and performance. MacBook Air includes a bright 13.3-inch widescreen LED display, built-in I-Sight camera, 2GB of RAM, 64GB Solid-State drive, and a powerful Intel Core 2 Duo processor with 4MB L2 Cache. Enjoy also a full-size Backlit Keyboard with keys that automatically illuminates from behind in low-light conditions, and a spacious solid-state Track-Pad with multi-touch gesture that lets you zoom, rotate, swipe, and scroll with just a flick or a pinch. Engineered for the wireless world, MacBook Air also comes with 802.11n WiFi, Bluetooth 2.1, and Remote Disc to deliver unparalleled wireless versatility to use any Mac or PC Storage drive. The MacBook Air Battery is our thinnest ever, yet it doesn't compromise power. You can access the Web wirelessly for five full hours. With MacBook Air, Mobile computing is a sensible reality.
