I'll withhold my judgement. Anyone who says it will be an absolute flop are just Debbie-downers. The cheap VR headsets I've tried are pretty cool, but there is a hump they need to get over in terms of capability and software. The resolution was too poor for them to be anything more than a novelty, and the games are kind of gimmicky (except the laser sward dance-fighting one)
With an 8K display, this headset makes it preferable when watching movies on a long flight. With the apple ecosystem we might have the first useful software package offered by default on a VR headset. The price is probably too high for 90% of the potential market right now, but imagine when it drops to the price of a phone. I bet a lot of people will find a capable highly portable display quite useful. The 3D aspect is kind of a distraction. Aside from gaming or 3D model design for gaming and special effects, I imagine a lot of people will be using it in ways that make the 3d capabilities somewhat moot, like comfortably watching a 2D movie while you're recovering form a cold in bed, or tracking your day -trading dashboards while using the bathroom, or putting the final touches on a presentation while in a taxi.
This technology is not the next laptop, phone, or watch. It's the next monitor. The first flat panel LCD screens couldn't compare to the higher quality CRT screens of the time. It took years for that paradigm to change. MAYBE just MAYBE this is the beginning of the shift toward VR headsets as a preferred display for a substantial subset of users.
