Think of the original Macintosh in 1984. How it was revolutionary, but limited. Think about what it grew into up until now. I remember. I was there. I felt the excitement, and I feel it with the Vision Pro, too.
In today's dollars, the original Macintosh would cost $7000.
A desktop computer faced none of the usability issues and subjective comfort and enjoyment that basically all current VR/AR implementations still suffer from.
When they get something as capable as the AVP into a form factor more akin to the Meta Privacy Disaster Glasses it will have a way higher chance of serious mainstream uptake.
Even then .. it has challenges that a desktop computer didn't.
