Apple has unveiled in Dubai the MacBook Air which will replace mechanical hard disks and optical drives with internet services and solid state flash storage. Available in 11-inch and 13-inch models, the new MacBook Air uses the same solid-state storage technology as iPad to deliver instant-on responsiveness, up to seven hours of battery life and up to 30 days of standby time. The new notebook uses Apple’s custom-designed flash storage which is 90% smaller than a conventional notebook hard drive.
