I can check the weather, get alert and listen to my music from my smartphone. I can enjoy some home automation with Canary (http://canary.is/). If I have free time I can design my own app and integrate a speech recognition to open the door (I am sure there are companies selling this too).
What unique "innovations" - conveniences will Google wearable (which at this stage seems to be just a watch) offer?
I say it has the same flaw as Facebook Paper because Paper 's success is based on rich, beautiful, poetic content. If your circle is casual writer, Paper will look lame to you. I love Google Glass because I can take pictures and record the world from a first-person view attached to my head. I don't plan on making a phone call directly from Google Glass yet - that's kind of weird.
So what else can Google watch do? I just can't see it.
The ability to better monitor your health and fitness.
You see, I can still get away with it with other accessory. I will give Google credit and say this is useful, but other than that, I really don't see it.
You know what is unique? What I want to see?
Iron Man computer screen + Iron Man interactive airtouch computer system.... That's what we are lacking. I want to be able to swipe through contents, web pages from thin air with gesture. We can do some of that already. Push it forward!
edit:
I will say this is useful as assistive technology. People who are visually impaired or motion disable can benefit from it. Just put it on wrist and good to go. But other than that, I just don't see it.
