Apple CEO Steve Jobs created a huge buzz earlier this week when he unveiled the new MacBook Air notebook computer at the MacWorld Expo. Besides its light weight, the unit is only about three-quarters of an inch thick, and Jobs, ever the showman, pulled it out of a standard yellow manila business envelope with a red-string tie at the top. Sensing an opportunity, two entrepreneurs have created a new “AirMail” sleeve especially for the unit. It’s made out of upholstery grade vinyl and lined with fleece. Selling for a reasonable $29.95, it’ll ship when the new Mac does, in about two weeks. See it firsthand (and mutter about not thinking it up yourself) at Manila Mac.com.
