An estimate by Concord Securities analyst Ming-Chi Kuo this weekend suggested Apple may have had a blockbuster first quarter of sales for the redesigned MacBook Air. Asian supplier checks reportedly saw Apple ship about 1.1 million of the 11- and 13-inch systems, or 38 percent of Apple's 2.9 million portable Macs. Kuo told AppleInsider he had previously estimated 700,000 systems shipping in a prediction just two days after they had been made public.
