The first of the MacBook Air accessories are already upon us. Belkin has come out with several covers. This one is the Expression Sleeve with shoulder strap, and others include the Vertical, the Slim-Fit, the Leather/Neoprene, the Neoprene, and the Slim-Fit with band. All of the cases are priced from $29.99 to $49.99 and come with lifetime warranties. The Neoprenes will be out in March with the others to follow in May. While there is nothing particularly unique about the cases, if you need to be official, this certainly beats your old MacBook cover.
