Twelve South has announced a redesigned version of its very first product, the BookArc for MacBook. Tailored specifically for the newest generation of MacBooks, the BookArc holds the MacBook vertically, freeing up workspace. BookArc for MacBook is compatible with the entire MacBook line including the new 12-inch MacBook, MacBook pro 13- and 15-inch, and MacBook Air 11- and 13-inch models. Like the original in 2009, BookArc is still $50.
