The new MacBook Air is the perfect laptop for the modern professional who’s always on the road. Featuring an all-aluminum unibody design, it has become Apple’s lightest laptop ever. The laptop measures 0.11-inches at its thinnest point and 0.68-inches at its thickest, and weighs just 2.3 pounds for the 11-inch model and 2.9 pounds for the 13-inch. It also features a multi-touch trackpad, extended battery life, and a high resolution display. Just like the iPad, the new ultra-light laptop uses a flash drive instead of a hard drive. The 11-inch MacBook Air comes with 2GB of memory and 64GB/128GB of flash storage. The 13-inch model will pack 2GB of memory and 128GB/256GB of flash storage. Like the 13-inch MacBook Pro, MacBook Air too features the NVIDIA GeForce 320M graphics processor. It gives over 2x performance over the previous-generation MacBook Air. It also packs Intel Core 2 Duo processors. As for the battery, the 11-inch model delivers up to 5 hours of battery life and the 13-inch model promises up to 7 hours. Both have standby time of up to 30 days. Apple is also bringing the FaceTime video chatting to Macs. The feature debuted this year on the iPhone 4 and has since been added to the iPad. The new FaceTime for Mac application, currently in beta, will let users make FaceTime calls over Wi-Fi with anyone who has a Mac, an iPhone 4, or the new iPod touch. Pricing for the new Macbook Air starts at $999 for the 11-inch netbook-sized model, and $1299 for the 13-inch model.
