It may seem a bit pricey at $899 AUD but if it works we can expect that price to fall. I actually like the fact these are cabled via a USB-C port (those supporting remote display) because that means they would work indefinitely vs the very short battery life you'd otherwise "see".
It will give you an effective 140" display screen in front of you, and seeing it is across both eyes should mean potentially 3D too.
This means that typical small display items like small phones and netbook size portable computers could be used with this virtual 140" display being seen. In theory, your phone could ring while in your pocket, you'd pull these glasses down on your head to quickly see who is calling, and use your voice to answer. But they are not AR, so you won't be walking around looking through these glasses as they operate only as remote display units which, yes, does limit their functionality somewhat.
