The more you learn about it, the more beautiful it becomes. Sure, MacBook Air is unbelievably thin and light. But we also designed it to be powerful, capable, durable, and enjoyable to use, with enough battery life to get you through the day.

Even at less than an inch thin, MacBook Air sets a pretty high standard – by making flash storage standard.
