Microsoft’s hololens2 is $3.5k available now for developers.
I think it would be aimed at actual designers and engineers etc.
Presumably they would partner with some key developers like Autodesk to have some apps ready at launch time.
The virtual workspace for hololens is the physical world. The view area is a bit small. But the idea is not in HL to create a virtual world, but to overlay information to the real world.
The latency tracking was on par with other headsets, which I consider quite good.
