I work in finance and talked to somebody who implemented a Bloomberg terminal wall in VR. This would be a great application for VR since you never can have enough Bloomberg terminals open and usually never have enough screen space.

However he told me that VR can not be used for anything productive right now because of many problems. One thing is, only very few people can wear a VR headpiece for 8 to 10 hours straight without getting serious headaches and dizziness. The resolution has to at least be one order of magnitude higher for meaningful sized fonts being properly readable. The head pieces have to be one order of magnitude lighter. If you want to do more than a 2D wall displayed like a canvas in 3D you have to solve the problem that your eyes automatically try to focus differently on different depths which is also one major source of headache.

All in all I was convinced by him that the VR technology is at least 2 generations behind what you would need for serious work. Until then all kinds of software, SDKs and Hardware will change dramatically. Hence investing in VR productivity software development right now is a complete waste of time and money.
