Re: Memory failure
The Hololens display was pretty unusable, as are all current transparent HMDs (rainbowing, stutter separation, washout, not to mention the tiny render area and inabilty to render black).
The Quest and AVP have a much better basic build for developing on, they could do with slimming down but the single biggest issues for me are the OS and software - AVP has none whilst the Quest is drowning in junk apps.
And nobody, I repeat nobody wants to use VR instead of having a a video call at work.
