I have played around with it, and the resolution just isn't there. The desktop space in VR is ironically less than on a laptop, because every window has to be massive to be usable at all. In a future with 2x4K res or something in that ballpark, this might be interesting.
I suppose that's an alternative use case for the tech - to simulate and get an understanding of how to build UX that is friendly towards those with poor eyesight. Haha.
