Apple launches MacBook AirThin and airy fairyBy Dean Pullen: Tuesday, 15 January 2008, 7:53 PMSTEVE JOBS IS usually full of hot air, but this time it might be of use.Jobs revealed the aluminum-bodied MacBook Air is 0.16 inches at its thinnest point, 0.76 inches at its thickest point and weighs just 3.0 pounds."When you first see MacBook Air, it's hard to believe it's a high-performance notebook with a full-size keyboard and display. But it is," said Jobs.Oddly we fully believed it.The MacBook Air features Intel Core 2 Duo power (1.6GHz standard, 1.8GHz optional), 2GB of memory, Intel GMA X3100 graphics, a 13.3" LED-backlit display and an 80GB, 1.8" HDD for storage.A 64GB SSD (Solid-State Disk) is also an option on the MacBook Air.The screen has a standard resolution of 1280 by 800, running on an Intel GMA X3100 graphics processor with 144MB of DDR2 SDRAM shared with main memory.To keep its thin form-factor, the MacBook Air contains only one USB 2.0 port, a micro-DVI port and an audio-out jack, choosing to remove the usual optical drive and ethernet ports.Other features include the usual iSight web-camera and backlit keyboard. Apple includes 802.11n WiFi and Bluetooth 2.1 as standard.As rumours suggested, the new MacBook also comes with a multi-touch trackpad, allowing owners to use the same gestures that iPhone and iPod touch users have grown accustomed to. µ
