Mainstream people don't seem to have much of an issue walking around with a hearing aid, I mean blue tooth device on their heads.

As for the watch, make it work like science fiction where you can raise your wrist and talk and I bet a lot would join in. I would not mind having a wrist device, even if it only queried my phone in my pocket, which I give simple voice commands. Bonus points to being a real phone.
