It's a cool tech device, looks nice. Bravo to the engineering and design teams and everyone involved that brought this to life.
But it's still not my cup of tea, I may purchase one in the far future but I probably won't be wearing one in the coming years.
I think your statement brings home a very big point. This device, while showing potential to be a game changer someday is probably just a "hobby" item for now. Hurdles for widespread adoption in this generation seem very high.
I have an iPhone, and it will be able to do most of what I would be able to do with the watch, and then some. The things my phone doesn't do, that the watch does are pretty niche, at least for now. I have a watch that I like a lot. It has a sapphire crystal, beautiful styling and is pretty much maintenance free. I don't have to think about it, and it generally just works.
My phone already gets put into the charger every night, and my current watch gets put on the dresser when I get home from work. I don't want to be without my watch because I forgot to charge it the night before, or have to remember to charge it every night.
I'm not saying I wouldn't buy this, but I would need to see it in person, and try it out in the store before I did. And there is at least a decent chance that even if I bought it I might return it.
