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. MacBook Air features a unibody design for both the main enclosure and the display. Unibody construction means a higher-precision, less complex design with fewer parts. And that translates to a notebook that' s exceptionally thin and light, yet durable enough to handle the rigors of everyday use.
