I can chime in on my first experience, and it was when the machine was still called Morpheus.
I had tried a demo at E3 2014, rushed to the line at the opening to get an appointment ticket for four hours later since everyone rushed for it.
They didn't have too many demos, so I got to try the shark demo where you're in diving cage and a shark attacks. It was blurry at first, but I was into it. The first moment that really got me into it was when I was just checking out all of the details around me, took a look to the left when the shark disappeared. All of a sudden, the shark was in my face to my right and I literally freaked out. It felt so real. I didn't need to be convinced anymore.
I'm going to get PSVR, but I'm just seeing how the economy goes since all of the Brexit shenanigans and the Canadian economy taking a dump this year. Maybe it won't be a launch thing, but I'll definitely get one. And maybe the Vive and Oculus are better quality headsets, but they don't have the games like Sony does.
