The W 3D smartphone could entice game lovers who want a handheld that splits the difference between a serviceable Android phone and a PlayStation Vita. The phone has four face buttons, two joysticks, a directional pad, a touch screen and — in a mark above the Vita — four shoulder buttons. It also has a glasses-free 3D display that uses eye-tracking technology. The 3D was spotty, but the 5.5" display itself looked quite good.
