Sony is showing off a mounting accessory for attaching an Xperia Z3, Z3 Compact or Z3 Compact tablet to a PlayStation 4 controller to use with remote play. By using remote play with an Xperia Z3 device, you essentially turn your phone or tablet into a wireless TV. You can play AAA PS4 titles over WiFi, while your PlayStation does all the heavy lifting.
It might be awhile until remote play and the mounting accessory are available but they do make buying into the Sony ecosystem a little more attractive. What do you think, would you rather be able to play your console on your smartphone, or turn your smartphone into a virtual reality headset?
