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. That's the difference between a notebook that's simply thin and light and one that's so much more. Thin, light, durable. Thank you, flash storage. Even at less than an inch thin, MacBook Air sets a pretty high standard - by making flash storage standard. Flash chips are very compact, 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 it takes 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.
