Q: Would You Pay $2000+ for Apple's AR/VR Headset?
A: No.
Depends what it can do, doesn't it? Without knowing what the SW is capable of, the question is idiotic.
But consider. Suppose that the SW is good enough (imagine eg Continuity and Universal Control extended appropriately) that these could extend your viewing field while working on an iMac to full 360 degrees around you, so that you could very easily work on very large spreadsheets, or see multiple windows, or view widely separated pieces of code.
Functionality like that, making you 5% more productive, makes purchase a no-brainer.
Or what if the glasses gave you superpowers, able to toggle between telescope and microscope vision, able to see UV and infrared?
Or you could have a shared/swapped mode, where I see what someone else's glasses are seeing?
Now will the device have functionality like that? Well, who knows? And that's my point.
All you are saying is "I cannot imagine glasses-based functionality worth $2000". And I am saying "that's a statement about your imagination, not about the glasses".
