The width and depth of the MacBook Air (11 inches) of -11.8 to 7.5 inches, is no different from what you get with Windows laptops like Asus UL20FT-A1 ($ 630 direct, 3 stars) Acer Aspire 1830T and -3721 ($ 700 street, 4 stars), but that Apple shaved in terms of thickness makes the others look like giants. It is difficult to assess how it is shockingly thin until you pick it up, cradle it and put it into the thinnest of the things you can find in the room. It is as big as the iPhone 4 at its thinnest part: The front edge, which measures a mere 0.11 inches, is in fact not so thin that the back of the unit (0.68 inches). It is thinner, no doubt, that any current netbook market.
The 11-inch MacBook Air knife edge frame is triumphant proportional to its weight, its 2.3 pound frame is slightly lighter than the Acer UL20FT-A1 (3.3 pounds), Acer 1830T-3721 (3 pounds) Dell Inspiron M1010z (3.4 pounds).
