The other poster is also right about resolution issues. To get any decent amount of text on the screen, you'll cause a lot of eye strain.
Another is that the force exerted on you head is roughly weight times the distance that weight is from the centerline of your neck. This multiplier makes stuff hanging out in front of your face much heavier than it would be if were just sitting on top of your head.
Waiting for my Piimax 8K-X to see what the greater and field of view and nominally better pixel density does for it.
I researched it for a VR application primarily for older people, so the ergonomics mattered, and the ergonomics were a real issue.
The best setup I could manage was to put the bottom of the virtual screen a bit in the floor, then you are looking straight on so that you can see the upper-left corner and still get to the menus and see at least the first ~25 lines of code (Consolas size 10).
I should note I'm using the built-in Desktop which you can insert via Steam VR Home. I just dropped it into the default home and moved it around/resized until I found it workable. There may be better tools for running virtual desktops in VR, I haven't explored this space at all since reading anything in any VR app for more than a few minutes makes me dizzy... speaking of which, no more VR for today! ;)
