I think identity confirmation is an essential technology. It's going to be huge, because it could solve the password problem AND the credit card fraud problem.
But the way to deliver that is putting biometric identity verification into the phone. Which is, of course, why Apple acquired a sub-dermal fingerprint recognition company.
This technology will obviously go into the phone itself and not into a lame peripheral that only geeks** would wear.
People who would not wear a smart watch:
1) People who don't like watches.
2) People who who do like watches. (and own Rolexes etc)
3) Women.
Disclaimer. I am a geek. But I wouldn't wear a smart watch.
I for one think this could definitely be a new market. I have read articles recently stating how the wristwatch market is in decline. I for one no longer wear watches unless it's a formal event. But I think the things a smartwatch could do, could change all that.
Examples I personally would love to see:
While using runkeeper I would be able to see what song is playing, check my distance/pace, all at a glance.
When sitting in meetings, playing video games, or at work, see who is calling/texting me at a glance, and even give quick responses from the watch without having to pull my phone out.
Misplaced phone? Simply use an app built into the watch to find it or play a sound (vice versa).
Driving? Don't have bluetooth in your vehicle? Use speakerphone on the watch and drive safely.
I 100% agree, there are definitely hurdles that will need to be overcome.
It will have to look amazing, give us the above abilities and more, and have great battery life.
But I guess arguing over this, really doesn't matter. We'll all see what happens sooner or later...better or worse
