Ed Zarick is at it again. The self-taught engineer has built a "laptop" device that combines both the Xbox One and the PS4. Custom built for a customer, Zarick calls his little creation the PlayBox. The device is a 22" laptop (case) that combines a PlayStation 4 and Xbox One into a single machine. Zarick's latest device is similar to his Xbook Duo design, a previous combo-unit he built that contained both an Xbox 360 and Xbox One.
