Apparently, last I heard (was a good year ago),
- the whole thing was overblown, overhyped, etc.
- tech nowhere near ready at the level of expectation they built. Basically was more limited than Hololens (narrow field of view) but some cool effects. Resolution/performance was apparently not good to see.
- Software wasn't much evolved either.
The entire thing was a borderline scam, despite big names etc. who apparently got hyped like the rest of us.
