I think it could be good for design in the sense of looking at how a finished product will look in a more human perspective, but for the actual design really all VR does is make your camera angle turn with your head and that's not super useful for most things. Your plain old monitor and mouse will be just as good for design. Better software is really a lot more important than if your interface is monitor/mouse vs VR/VR stuff.

VR is really just a display and input technology. It doesn't add much ability to computers that isn't there with a monitor and mouse. If you had head tracking software that moved the monitor image with your head you would get most of the wow factor of VR just like that.

I worked at an engineering company doing IT. I don't see how VR would help them. It's a lot of number entering and checking measurements against other records, dual monitors are nice and many still use paper and have to do field work and then bring that data into the design tool like AutoCAD. Soo VR seems like it would just get in the way of multitasking so bad it would suck for most real productivity uses. Like if you think about how most any office works.. VR sucks for that.
