I see a lot of "I can already do the same things on my phone" posts, but that doesn't close the book on smartwatches for me.
A phone can do everything a tablet can do. A laptop can do everything that a phone or tablet can do. A desktop can do everything a laptop can do. Go back to the start of microcomputers and there is the "the office mainframe can do everything a PC can do" argument.
All of the above platforms succeeded because they helped people do mostly the same things (or a subset of overlapping things) but added some advantage in portability, cost, ease of use, etc.
Google's official vision for Android Wear is interesting because it clearly explains where Google thinks the advantage for watches will be: timely notification of important information *without* interrupting what you are doing. If you're not understanding why you'd want to own a smartwatch, it is worth reading:
I wouldn't say the current crop of hardware and software delivers this vision all that well, but if this is the goal then I will remain interested. Apple's strategy seem less focused and more of just "hey, it's yet another thing like an ipod or an iphone or an ipad, but tiny". Maybe that isn't accurate, I haven't spent as much time reading about their platform yet, just a first impression.
