Personally, I don't believe the business market actually exists.
I always hear people giving made up use cases like "oh, service engineers will be able to see instructions overlaid on the machines they're working on" but a paper service manual costs a lot less than a 3D augmented reality manual - and anyone who's worked with service engineers knows for any repair that's performed often enough that productivity is important, the service engineer will know the process by heart.
Oh sure, you can sell a few units to architecture companies that want to dazzle rich clients. But you can't sustain a product like this on sales of 1000 units per year.
Google Glass and HoloLens both targeted the "business market" but that's just them saving face when they can't hit a price point that makes any sense.
