I think they are a good idea, like some said in cars and such, but what really gets me is to see people in resturaunts with them on or in clubs or places like that. They aren't even talking at the time they just have it on in case. What fucking TARDS. I just wana walk up to them and start doing the robot because they look like cyborgs! Once i saw a couple eating dinner together in a nice resturaunt and they both had them on. I couldn't help but laugh...
