> but why would I want to have a device on my head to look at a 2D canvas?
Office managers are sooner or later going to find one VR headset cheaper than 2 or 3 large screens for tech work. At that point, you will be given a headset instead.
I think the point here is the availability of unlimited screen space. Everywhere you look can be a monitor. Combined with the potential increase in productivity, and the use of VR offices for remote work, I can see a business market developing for this. I don't think we're ready to say monitors will go away. But I think all the pieces are there for VR headsets to be adopted by some companies once the resolution gets good enough.
You still can only focus on one monitor/window? The only difference is that you switch focus/windows via head tilting instead of keyboard/mouse, so I don't really see what that buys you.
