Twelve South makes cool, if simple, laptop gear. We’ve covered their BookArc before and this is an improved permutation of the version for the latest MacBook Air. It costs $39.99 and allows you to stand your laptop up next to a monitor and control the cabling so everything is in its right place.
From the product description:
Like previous versions of BookArc, the MacBook Air model is fashioned from heavy gauge steel for stylish looks and a sturdy footprint. One convenient addition is built-in cable management. 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. These cables stay tethered to the stand so you can easily get your Mac in and out quicker than ever.
