I've relied on USB docks to expand my laptops' connectivity options, both in my home office and on the road, for years. This new one from Cabletime adds a surprisingly versatile screen to earn its keep on your desk. The ScreenDock adds a 5.5-inch 720 screen to your setup that you can use in all sorts of ways. That way, you can display anything from your computer on there. USB docks are indeed a dime a dozen (and this budget pick from Anker is pretty solid).
