The latest ones do have solutions for that (head locked vs space locked displays). This also was one of my requirements, but now I'm actively considering them. The main thing holding me back now is that the tech is improving so rapidly that picking a time to buy in is hard.
I tried these with much excitement. Unfortunately they give me immediate eye strain and headaches. The optics need a tremendous amount of work. 1080p is also not enough. But some people love them. It’s a product you just have to try and see if it works for you and return if they don’t.
It works with phones, too, which is cool!
