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.
