True.

"Now, the logic is that whoever pours the most money into it will win the race and with patents be in a monopoly position."

This is not quite true :).

My bet is that the quality of AR that we see in their hype videos will not be possible on a consumer scale until after the core patents have run out :).

This is a 'disruptive' technology but it's still way behind practical applicability.

We see this in every industry - and sometimes it takes quite a long time for products to come to fruition :)

In addition the lack of 3D isn't that big of a deal given the brain fills in the details with other cues. E.g. People that go blind in one eye can adjust quite well to the lack of 3D.

I personally would love a HUD for my sporting activities; e.g. Skully. But my phone is perfectly fine as a daily driver.
