Alice Hill has a great feature on how Bluetooth headsets are the new anti social device in that they scare the locals. As you walk and talk, no one can see the hanset and thus most feel that you are talking to thin air.
I have said for sometime that the arrival of Bluetooth headsets means that we are coming closer to that Star Trek moment when we push a button on our clothes and start talking. I find my HBH-660 headset pared with my K600i from Sony Ericsson means that I am safe walking and talking in that in enables me to use my phone in the street without running over people!
I just want the designers to make the headset even smaller, how long will it before before I am once again have an earing just this time it's my headset?
