Well, since we're talking about how weird or geek or(name your adjective) wearing full-size cans in public may appear, why does Bluetooth get a free pass here ? I can't count the number of times I've seen people walking around having a conversation w/ an invisible person before you realize the phone is in the ear on the other side ! Even if you can see the phone how is this more socially "acceptable". This might come under the heading of how people from different generations view things & how important public image is to you. Maybe some of us become a little less social as we age. I seem to remember how important it was to congregate in large groups of people when I was a teenager, you generally hung w/ your sub-group of friends, but there was quite often a larger group wherever we were. It was all part of "hanging out". I think the "having time to kill" factor does'nt exist to the degree it did when we were young factors heavily into living our adult lives. When I do have some free time I don't really get too concerned w/ my public image that much anymore. What's the saying? Actually there are two that come to mind "Been there, done that" & "It was real, but that was then,this is now".
