Smartphones have grown bigger and bigger each year—but they’re still subject to the size limitations of the human hand. The LG Wing ($999) has found a way to continue the phone-size arms race with a device that, at the flick of your wrist, opens up into a T-shape, revealing a second screen. Users can leverage their extra square inches of real estate to multi-task by opening up a different app on each display. Reviews are mixed on how useful the forward-thinking feature is, but it’s certainly innovative. —Billy Perrigo
