Android fully understands the idea of running multiple apps, at different resolutions, simultaneously and yet, no product in this space due to I assume restrictive APIs.
The nReal glasses will act as a monitor for your phone.
It's not as easy as you think though. Streaming video at acceptable VR resolution and framerate isn't trivial.
I guess you could get a headset to act like a car and get Carplay running, but full RDP of an iPhone...does anything do that?
Like iPhone mirroring?
I have left the Apple eco system for the most part, but I remember 10 years ago demoing on my Mac what was happening on my iPhone.
It has its own apps and it's own browser. I tried opening a couple epub readers but trying to open a file didn't bring up any file open dialog from the browser.
I felt pretty bad for the headset makers. Quite clear they were entirely beholden to an Android where most apps have extremely limited capability sets, where they have to really reinvent the universe afresh for their headset.
