Apparently, the Macbook Air is selling well enough to be unavailable in many stores and require a 5-7 day wait for online orders. Despite the high price, the super-thin laptop is often selling out the day a shipment arrives at an Apple Store according to research done by Ars Technica. Of course, without knowing just how many Macbook Airs Apple is manufacturing, this could just as easily be a case of Apple not making all too many in the first place, making demand seem higher than it really is. What do you guys think, have you seen lots of them out in the wild or is this just a case of distorted perceptions? [Ars Technica]
