A wireless network of jewelry

SonyEricsson and Fossil have been doing some interesting partnerships in the smart jewelry area. This one connects via bluetooth to your phone and gives you updates about what it is up to (see original InfoSync article). It is supposed to give you caller ID info, inform you of incoming text messages, manipulate your mp3 player and let you answer calls.

I've been saying for a long time that watches and rings should be light-touch interfaces for a limited quantity of other devices and services. But why do you want to access a call from you watch when you can't talk into the watch? Your phone is still in your pocket. And why such a small screen? I know that the analog aesthetic is in, but why not an analog clock on a digital screen and then you have more screen real estate to actually put in the name of the person calling you in a large font? The mp3 scenario sounds more reasonable, but then you start to wonder if the mp3 player shouldn't be in the watch itself, and not in the phone.

What I do like about this watch is that it looks like jewelry and not a gps or a dive watch. I ran a study a while back where teenagers were absolutely loathe to wear a prototype for a few hours simply because it didn't look pretty. This isn't a bad looking watch even though it probably isn't all that usable or useful. Also, the peer-to-peer possibilities haven't been explored here. Lots of people walking around with bluetooth watches that can communicate? There is mobile community potential here. And why does it only connect with the phone? Why not the TV and the stereo and the front door and the lights?
