Even at less than an inch thin, MacBook Air sets a pretty high standard -- by making flash storage standard. Flash chips are very small, allowing MacBook Air to be incredibly thin and light. Flash is also solid state, meaning there are no moving parts. Which makes it reliable, durable, and quiet. And because Apple placed the flash chips directly on the logic board, they take up much less space -- about 90 percent less, in fact. That creates room for other important things, like a bigger battery. So you have a notebook that weighs almost nothing and runs for hours on a single charge. That's mobility mastered.

Multi-Touch technology is part of practically every Apple product. It's the best and most personal way to interact with your devices. And the optimal way to experience Multi-Touch on a notebook is through a trackpad. That's precisely the case with MacBook Air. The trackpad's spacious, all-glass surface doesn't have a button because the whole thing is the button. And with Multi-Touch gestures that are new to OS X Lion, you can interact with MacBook Air in ways that feel more intuitive and realistic than ever before.

Anyone can try to make a notebook that's thin and light. Success comes in doing it without cutting corners. That's why MacBook Air features a full-size keyboard, not a condensed version of what you're used to. When you type on the MacBook Air, it's just as comfortable as typing on a desktop keyboard. And now the keyboard is backlit, so you can type comfortably even in low-light conditions. A built-in sensor detects changes in the ambient lighting and adjusts the keyboard and display brightness automatically, giving you the perfect illumination in any environment.
