The laptop will compete with a range of portable devices, from companies such as Sony, Dell and Asus, which are already building so-called sub-notebooks, designed to be lighter and more mobile. The MacBook Air also has a 13.3-inch widescreen display with 1,280-by-800-pixels resolution. It also includes a built-in iSight camera.
How did Apple make so thin laptop ? Well, a combination of factors went into the MacBook Air’s design. Its main circuit board is remarkably small—Apple took a photo of it next to a pencil for comparison purposes—and packed with electronics. There appear to be no accessible RAM slots. Most standard Mac ports were omitted.
There’s no optical drive. Apple even had to call in Intel to create a special, smaller version of the Core 2 Duo processor. And the battery isn’t removable, which allowed Apple to save a lot of space by omitting a battery-access compartment.
