BookArc for MacBook Air has been released go and get it if you want..
Book Arc is made of heavy gauge steel that can keep MacBook Air snug, this Twelve South release turns Air into ultra thin desktop and it has its own built in wire management system for and easy cable use.
When BookArc is paired with Air and an external monitor a boost up in the display is noticed that is very precise for graphic applied programs. Its shipping is done only for $39.99. When a monitor is used with Air left open the video memory is ditributed among the two displays. But when working with BookArc in resting position and closed Air seems to utilise its 100% memory onto the monitor.
