In December 2016 I tried a demo of an HTC Vive at a Microsoft Store (remember those?), and a few days later did a demo of an Oculus Rift at a Best Buy. The demo at the Microsoft Store was well set up - they had an associate handling the demo, an area set aside to do the demo, a speaker, and a display to show observers what was being shown in the VR set. The Best Buy demo was not as put together but was still OK.

Not sure why they seemed to be demoing it more then than now.
