Twelve South (http://www.twelvesouth.com) has introduced a new version of its BookArc, designed exclusively for latest MacBook Air (late 2010 models). The new model grips the thin MacBook Air and includes a built-in cable management system to keep cables in place for “grab and go” use.

When BookArc is paired with a MacBook Air and external monitor, it offers a noticeable boost in power for graphics-intensive programs, says Creative Director Andrew Green of Twelve South. BookArc for MacBook Air begins shipping next month for US$39.99.

Like previous versions of BookArc, the MacBook Air model is fashioned from heavy gauge steel. Since MacBook Air has inputs on both sides, the BookArc cable housing routes power, external display, USB and other cables behind the MacBook for a clean workspace.
