BookArc is the little MacBook stand that makes room for a big monitor. How? It holds MacBook vertically and off of your desk. Set your MacBook atop BookArc, plug in your favorite external monitor, keyboard & mouse. Now you have taken a compact laptop and turned it into a comfortable desktop setup for your home or office. Things like photo editing, spreadsheets and other projects are easier to see on a bright 24-inch (or bigger) screen. When it's time to go mobile or head out for a meeting, unplug your desktop connections and the BookArc Cable Catch will keep them in place for you.
