Concord Securities analyst Ming-Chi Kuo revealed on Saturday that Apple shipped a total of 1.1 million MacBook Air units over the course of the refreshed laptop’s first quarter of availability. Though the firm’s figure is most certainly not confirmed by Apple, Ming-Chi cites channel checks in Asia in revealing shipment numbers, which would make the new MacBook Air one of the fastest-selling Mac computers in Apple’s history. Ming-Chi notes that sales have likely begun to slow in the first quarter of 2011, and Concord estimates that Apple will ship approximately 700,000 units this quarter. Shipments of Apple’s newly refreshed MacBook Pro computers are expected to make up for the slowing Air sales, however, and Concord notes that demand for the new Pro line will help offset slowed MacBook Air shipments.
