Smart watches are still trying to solve a problem that doesn't exist. They don't do anything that my far more capable phone can't already do. Sure, it may be nice to respond to a text with voice commands but voice-to-text messes up a lot. It doesn't even matter what platform you're on. There's still a niche there though. For example, GPS while biking, exercise tracking... checking the time??? IMO, what smart watches really need is a SIM card that links with your smartphone. For example, you're at work but you left your phone at home. All your messages could still be pushed to your smart watch. Then you could leave your phone at home without leaving your phone at home. I think that would open up a whole new door of possibilities.
You can have that now.....just get a cheaply made China Android Smart Watch.
More stuff..more space required, also bigger battery required, both add bulk.
The concept is to have a flow, to follow how things are an extension of some thing. A watch only needs to be an extension of the phone, much like a finger is an extension of the hand.
You start adding things into the watch and your eating up power. Right now people are outright enraged if you have to charge something at the end of each day. Something most do now with a phone any way.
You need to off load the grunt work to a phone, allow the Phone to become the watches brain. The watch should have only a set number of functions. Mainly Gather readings from your body and display information the phone provides to it. Simple interactions with SMS/Email
Yes add in Cortana, but it does not have to be full load...again have the guts of Cortana in the Phone, with base set of functions in the watch.
The Watch by itself should only act as a Watch, with what ever few functions it needs to do so. Time Keeping Day Date Month stop watch.
Now pair to a Phone and more comes into play...Weather/News Buzz Words/Sports Scores or any number of handy items you set on the phone to send to the watch. SMS/Email Alerts, Who's calling display and alert ( I don't think it really needs to handle the call, but maybe a feature someone wants). Media Play controls only ( does not need to show video and blast audio).
The Watch should be the Phones second screen almost, but does not need Super Hyper Mega Turbo Retna display.....no need to watch Netflix on a watch. However not so low res as to be like the old Pocket PC pixil popping days.
One last thing........Have you taken total leave of your mind???????????? Leave my Phone at home?????????? I'd be a bloody nervous wreck and never get any work done.
That is like telling a crack junkie "Here is all the crack you could want.......just no pipe".
