That said, you don't really notice this effect, or much else, once you're immersed in something. I've hundreds of hours in the vive and I still punch walls, the ceiling, lean on objects that don't exist.
The point is that regardless of the various things that would make it better (4k light field displays, bigger fov, higher refresh, blacker blacks, etc etc) the tech is good enough today - the fact that one is able to surrogate away from "I am stood in my living room wearing some silly goggles" to "I am stood in the snow atop a peak watching the sun set, I should get inside or I'll get cold" is the litmus test. Literally everyone I've jammed in it, young and old, has lost themselves in it.
I read an article at some point that claimed this was an issue so I consciously tested it in the unit - focusing on something near my face and then farther away without moving my head and it actually feels (to me) pretty correct.
I don't really know the science behind this versus light field displays or whatever, but if you have access to a unit I encourage you to try it - it's very difficult to detect issues with focus and it absolutely does not look flat (again, to me).
I would be very interested of all the opinions in this thread which of them are from people who own a unit and have tried these things and which are assumptions.
This technology is so incredibly convincing I'm embarrassed to say that I fell over trying to lean on a virtual pool table at one point. I simply forgot that it wasn't a real thing. :)
