Nothing stops me from having multiple windows on my 13" desktop. But it's clunky to bounce between, and makes me lose context too easily ctrl/alt+shift/+tab/~/1/2/3-ing through my browser or text editor or output window. With a multi-display, I can just turn my face over or glance and look at what I need and be back in context right away. I mean, I hope I don't have to explain why multiple monitors are nice (for most people). The same is conceivable with a VR solution. That makes it awesome. As for the problems you mention, all extremely solvable. I'm sure you were alive when people were editing text on lower resolution displays. Lens technology for dealing with a great extent CA exists, it just needs to be tuned for VR settings. I could lie down and use it. Lighter materials could be used in future versions. It could be made disassemblable for easier packing/storage. I have faith in our current generation of technologists to make these things and more happen before my development career sunsets :)
