Facebook on Wednesday unveiled the Oculus Quest, the company's long-awaited, standalone virtual-reality headset that will go on sale in early 2019 for $399. I had a chance to try out two demos on the device.

The Oculus Quest's main advantage over other standalone VR headsets is its motion tracking technology. Unlike other portable headsets, the Quest is able to determine the motion of user's head turns, hand gestures and overall body movement.
