MacBook Air is currently the world’s thinnest notebook in the market, measuring a mere 0.76-inch and 3lbs. 
It has a 1.6GHz Intel Core 2 Duo processor, 2GB of memory, 80GB PATA hard disk drive, 13.3-inch glossy widescreen display, keyboard with backlighting, iPhone-like multi-touch trackpad, 802.11n Wi-Fi, Bluetooth 2.1+, and a 5-hours battery life on Wi-Fi.

However, it has some drawbacks.  No optical drive,  but it has a new Remote Disc feature, which is a software that you install on another Mac or PC on your home network, and it automatically shares that computer’s optical drive with your MacBook Air, or you can purchase the optional external SuperDrive at US$99.

Price: US$1,799.
