Lessons learned on the Lisa were applied to the Mac for less money to sell to more people. I suspect the same thing will happen with their VR/AR/XR headset.
They only got a second crack at it because they were floating on sales of the Apple II. If the Lisa had been their first product, we'd be saying "Apple who?"
The Vision is a whole different universe… with their cash and position they could (and may) take 10 cracks at it.
Doesn't make the tactic any more or less relevant...let the people with money and motivation become the first real-world usability testers, then optimize for the rest of the population.
I struggle to see any sizable market for the tinybox, but I wish them good luck.
