Games and stuff are nice, but everyone I've known that uses a vive or oculus gets tired of needing to move around in VR pretty fast.
But being able to get rid of the 3-4 screens on my desk, and replace them with a headset that I wear? That I can put windows everywhere? Behind me, far left, even throw one up above me to glance at? That's HUGE imo. And the cost can quickly make sense.
I'm in the market for a new set of screens for my machine. I want to go to 4k. I'm looking at realistically $1500 for new screens. If something like Magic Leap or hololens was only 2x more than that and could get even "1080p equivalent" resolution compared to my screens, i'd happily drop the extra cash right now.
Yes, it's still not at that point as far as I can tell, but I don't think needing to increase resolution a bit is going to be the thing that ends up making VR/AR "impossible".
