macbookair
The macbookair was designed to balance both performance and portability, consisting of a full-sized keyboard design, a machined casing made of aluminum, and a very light and thin structure. The macbookair is available with 13.3-inch and 11.6-inch displays.
The macbookair sits below both the thicker, higher-performance macbookpro and thinner, lighter new macbook. The macbookair has become the best-selling macintosh computer and the best-selling ultraportable notebook. It continues the powerbook duo series from 1992.
