"That refresh rate is annoying, which is a shame because lots of people put lots of effort into making this artefact"
"So flat and pixelly"
"Why am I sitting inside a sensory simulation box when I could be doing more exciting and fulfilling things in that-which-we-refer-to-as-the-physical-world?"
"The faster you move your head, the more the graphics lag behind the sound... Woah, try it with the music visualizer, it's like multimodal flanging or some shit"
I have had the opportunity to play with Vive headset. The lag is hardly noticeable and once the drugs kicks in it should be more tolerable(i am guessing :P).
And for some the physical world is too boring anyways, So might as well be trapped in the sensory simulation box.
The real issue would be the ergonomics and the walking part to create something with the brush.
