The Galaxy watch that Samsung has integrated with their phones so that you can actually answer and talk with it intrigues me as a Dick Tracy fan, but that novelty isn't enough for me to buy one. I think Samsung's take on this is the most relevant I've seen.
THAT said, I don't see this smart watch thing actually taking off. I think Apple with put out their obligatory offer, but ultimately I think this is where we'll see the smart accessory market taper off, and as such, it's tie-in with the smart phone market. Wearable tech only makes sense when it's actually practical (that sounds like a an oxymoron, I know) and serves a purpose.
So far, every suggestion I've seen seems to be that this is basically an extension of my phone. Like the LG pic above, I don't need to see pics on my watch. If I have time to pull up pics on my watch, I'll pull them up on my phone instead.
What I'd like to see is the integration of a *small* smart watch with something like the Jawbone band. I don't need pics and video and crap, just give me a Dick Tracy watch that can monitor my stats and optionally send them via bluetooth to an app on my phone and also stores them locally to download later.
I think instead these smart phone manufacturers are trying to do the phone tie-in to force propriety, which goes completely against the Android philosophy and what makes it competitive with Apple.
