Macworld.com.au is reporting that a refresh of Apple’s Macbook Air is scheduled for tomorrow. Having successfully tipped the last Macbook Pro refresh a week early, Macworld’s source has a proven track record when it comes to Apple laptop refreshes. The source claims the new Air will have the Apple part number MC516LL/A K87 BETTER BTR-USA, and is already visible in Apple’s inventory system. The source goes on to say Apple may also announce a new 27-inch LED cinema display to compliment the 24-inch model already available. We would like to see a MacBook Air packing, at minimum, a Core i3 and 4GB of RAM, oh…and a 27-inch display that actually works would be nice.
