This year's MacWorld has arguably stolen the limelight from CES. At the conference, Apple unveiled their new range of computers, including the world's thinnest notebook, the MacBook Air. This computer is only 0.76 inches (1.93 cm) thick and has an electroplated aluminum shell, providing an excellent feel. It also features a 13.3-inch screen (with a maximum resolution of 1280x800), offering a display quality that is not much different from a regular Apple MacBook. The price of this computer is USD 1799, and you can pre-order it online via Apple's official website right now!
