Google cardboard is used to develop the apps without expenses, it partly solves the chicken and egg problem. The hardware for glass v2 is secret and is not out yet.
Glass is 3 years old, and was an experiment trying to make the smallest and lightest device wearable all day. It's all about compromises. The software and API are one thing, and the hardware is another. You don't seem to understand it's just a choice of making a huge headset or a tiny one. Android will have many many vendors giving all the choices just like they did with phones.
You misunderstand my position. I absolutely believe in AR, it's the next frontier after VR. But I think I understand at least some of the technologies and the limitations involved. I studied diffraction and interference when I was yonger, and I still have my Argon laser (with a stupidly heavy 1000 watt power supply), which was my go-to laser to study optical stuff. When I say study, I mean play. Play with fricking lazer beams and diffraction gratings and holographic plates.
For hardware there are still major compromises that MS didn't solve. In fact MS just made a headset. They are stuck with the same compromises as everybody else.
For software and platform, I don't see a vendor lock in as a plausible scenario for wide spread adoption. I don't see what windows 10 can do to stop the Android freight train.
The technology that will unlock AR is magic leap. It is years away. In the mean time we play with what is available.
Please don't forget you were the one who thought oculus would be 4k per eye, and I said it wouldn't be more than 1440p split in two. It ended up 1200p split, barely 12% better visual acuity than morpheus. Because there are absolute limitations that applies to everybody in the field.
