Apple is facing a rare instance of sellouts for the new MacBook Air, according to some of our own early retail checks. Several Apple stores, including a local store in Ottawa, Canada visited by one editor as well as others in the US, had sold out of the base 11-inch and 13-inch models by the afternoon. Stores were seeing exceptionally high sell-through rates for what they were used to with Macs; one medium-sized quoted Electronista about 60 to 70 Airs per day.
