The question I have is, what if the novelty wears off faster than the technology can improve? I think that is especially true of niche items, and has been the problem with 3d tv's. I also see is it happening with VR. However, in all fairness, one example of VR's performance from the past is not enough to establish a definite pattern, so I guess I will also wait and see before drawing any firm conclusions. I am rather skeptical though.
I should also mention that while I have not tried PSVR, I did try Sony's HMZ-T1 movie viewer HMD at the Sony store. It looked pretty damn cool in the commercials, and I was actually considering buying one over a TV. However, after trying it out, I recognized all the practical problems with it. Despite that being in 2011, I really don't see the technology changing substantially in the greater scheme of things, over that period of time. As I was saying, this may be a compelling purchase in a few decades. As it is, I think myself and a lot of other people see better ways to spend their money.
