From The Verge’s forums:
At it’s best, Android Wear is nothing more than a notification drawer slapped onto your wrist, coupled with a couple of Google Now cards. That’s it. Everything about it derives entirely from your smartphone, not just it’s ability to connect to a network, but also the very information it presents, the actions you can take, the visuals you see and the content as well.
I own a Pebble and I don’t really disagree with this. I’m pretty sure I’ll end up with a Moto 360, because it does what my Pebble does better, and looks way better doing it, but it’s still very much a niche item and I’m not sure there’s any single killer feature that will change that for consumers any time soon. For some, like me, “a notification drawer slapped onto your wrist, coupled with a couple of Google Now cards” is actually invaluable. For others, it’s useless – and that’s fine.
Though there’s no one killer feature, I do wonder if, as Google’s knowledgebase expands and Google Now gets better and does more things, Android Wear will sell itself based on Google Now’s predictve abilities. Cards on my wrist with immediately relevant information are way, way more useful than cards on my phone – and that could, in the long-run, end up being Google’s “killer app”.
For what it’s worth, I do think smartwatches are a case of “don’t knock it til you try it.”
