I think Google should make Wear 100 percent voice. I just realized I don't want to be swiping with my left finger (or right I'm cross dominant) on a tiny screen. Also, get rid of the whole bluetooth thing. Having to be in a relative vicinity for your phone/tablet is dumb.
Other than that its very exciting and I will be keeping an eye on it
It pulls notifications from your phone, so it has to be connected to the phone and bluetooth is the best way to do so.
100% voice? That would be a disaster. There are many times where talking to your watch is not convenient.
I agree with others about battery life. It is the one thing that will probably annoy me. As far as outside visibility is concerned, I am sure you can see the display it just looks washed out and is hard to see. Even my pebble is harder to see outside.
I cannot imagine the moto improving that much on battery life b.c the technology does not exist. Battery technology will need to improve or else we are going to be stuck with these 1-2 day watches. Until someone decides to use a solar powered watch this is what we have.
