Instead of assembling a notebook from many minor parts, the new MacBook was re-invented from just one: the new, solid-aluminium unibody enclosure. It gets full credit for making MacBook thinner, lighter and even more stunning. But itís not all beauty. Because of the unibody, this MacBook is more durable than ever. It was designed to take on your world. So slip it into your backpack or briefcase and pull it out wherever you go itís impressive in any setting. Even the keyboard is advanced. The MacBook keyboard is solid, responsive and comfortable. Just put your fingers on the crisp keys and youíll feel pure typing bliss. An illuminated keyboard, a popular feature of MacBook Pro and MacBook Air, now comes standard on the 2.4GHz MacBook model. So when youíre in low-light settings such as airports or lecture halls, you can always see what youíre typing. Itís a luminous feature for anyone on the go.
