Wearables are destined as peripherals, precisely because it only makes sense to choose a wearable over the computer itself when the ergonomics and use cases are superior.<p>So a cell phone watch is a trivial non-starter.  But a bluetooth watch, subservient to the phone, delivering accurate time, calendar information and message notification without having to reach into your pocket and enter your lock code, is a different thing.<p>Similarly, a necklace recording device would be ideal for hands-free audio/video recording to your primary device.  Who wouldn't want a trip video they didn't even have to <i>remember</i> to record?  Not to mention a necklace/earring combo that acted as a bluetooth headset.<p>Eyewear definitely has a lot of promise, but I'm not entirely sold on it needing to be inexpensive.  People pay <i>a lot</i> for stylish eyewear.  So I don't doubt people will pay quite a bit for eyewear with features.  However, it also suggests that eyewear electronics are dead in the water until they're stylish.<p>The watch and jewelry really isn't that far out there.  Particularly during years when chunky jewelry is in style.
