The idea of a portable large viewing screen is brilliant but that it not the real main selling point of this. A decent VR head set could do something similar.
In 10 years time, comments like this will either look like a prophet that could see the folly of the future... or be like all those people that dumped on the iPod and iPhone.
Are there any VR sets & OSs that can project multiple app windows into the space around you?
It is conceivable that completely different categories of workflows will become available. In the end everything we do on a computer has been invented at some point or another. I guess there are plenty of eager early-adopters and fanboys that will be more than happy to report on their magical productivity boosts.
In any case, assuming that the above caveat is not an issue, if the main real use case is as external monitor replacement I would think that suitably optimized hardware would deliver much better value for money. No need to wear a computer on your head when you need to carry one on your laptop (even mobile) anyway.
I’m also not really concerned about value for money. As far as business expenses go it wouldn’t exactly be a major spend. I’m personally more concerned about how good the experience is, and value for weight and size. For about half the days in the year I have to live with ~35 lbs of possessions that have to be able to fit in a suitcase. So for me if it could deliver sufficiently improved work experience it would be worth it.
