Pokemon Go isn't real AR though, it's just a phone app that uses the device's camera. You need dedicated hardware to do real AR. I'm withholding judgment until I see that.
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.
