Depends on software, was messing around with SimulaVR. It's cool though needs work. I was using the Index it could be better on resolution/text focusing.

I would not use it for productivity because it's a new environment/more distracting than useful. Also turning your head a lot to look at things.

I like my curved ultra wide monitor.

When the physical SimulaOne comes out I'll try it out again that one is not tethered/better quality eye display.
