AR/MR for productivity is simply not disruptive enough to displace existing options for most people. If I need a portable screen a much cheaper tablet will usually be good enough. If I have to take a keyboard with me anyway then a laptop would work just as well. If I need to show something to people then a projector does a good enough job, there are even portable ones too. If I need multiple large monitors I will certainly need them for more than the 2 hour Quest pro battery life and I'd really rather do so without the discomfort of wearing a headset at all. I don't see much utility in moving my entire virtual workspace when remote support and meetings are becoming the norm. 

The only business usages where the shortcomings are still justifiable are virtual training and 3d visualization, both of which have already established niche markets at this point.
