In my opinion, wearable tech is stupid. Bluetooth ear pieces being the exception. I guess we have to call them ear pieces or ear sets now. Headsets aren't specific enough with products like Google Glass on the way.
People were criticized for looking at their watches too often or at inopportune times, like when someone is speaking to you.
People were criticized for looking at their phones too often.
Now people will be looking at their watch that tells them to look at their phone.
With Google Glass, more and more people will be staring off into space, saying "huh?" all the time.
I can't wait for wide adoption of wearable tech, if I were a pickpocket.
