One of the problems it did have that I thought was a problem for adoption was that it didn't handle being lent out very well. If you calibrated it for yourself, it was pretty responsive, but hand it over to someone else, and it was out of whack in didn't really respond. I lost count of the number of times I'd show someone something cool, hand it over to them to try, and have it not work on them because the calibration wasn't suitable. Understandably, this left them with the opinion "this is shit".
It was a marvellous bit of well-made kit, had a couple of problems, and as you say, was in the first generation of it's kind.
Originally. Then they started to sell it on the play store for $1500 with a full marketing page and no explanation that it was a beta product.
Certainly the time they released it to the UK market Google would have known that they were selling an evolutionary dead end as if it were a product.
I would assume this was more an act of internal political cowardness at recognizing reality rather than grubbing for money.
Marvelous other than the 1500 dollar price tag for an unfinished product, the lack of software, the abysmal battery life, and the obvious privacy concerns of this device being constructed by one of the most invasive companies on the planet?
I agree with the fact that it's the first, but calling it marvelous is a bit of a stretch.
Personal HUDs or Google Glass etc will go through the same steps. Something, maybe not totally similar but something with a camera, a HUD, augmented reality, and hands free controls will happen someday and will become as mainstream as smartphones are today. It might be 5, 10, or 15 years down the road.
