Yeah, this is pretty much what I'm hoping to see as well. Something useful, light enough to wear for extended periods of time and provides a sharp, clean picture comparable to, or better than, current monitors.

Even if it's low resolution, as long as it's something I can look at and wear for extended periods of time without my eyes falling out or ears falling off, it'd be interesting.

What I'm not interested in is a face-attached TV/games console/billboard/social media interface. Yet that's what I fear most firms are looking to create, because it benefits them.

the current generation of vr headsets aren't useable for extended periods. too heavy, too hot and too clunky

losing peripheral vision is a bigger annoyance than i expected also

Try looking up NReal Air. Not 4K, but usable.
