It'd be kinda doofy holding it up to your face to talk... you'd probably want a blue tooth headset, but I could see it being pretty cool for wearing while you're exercising or something. Then again, I guess you'd want wireless earbuds or something otherwise you'd have a cord slapping all over the place.
Soooooo... overall I dunno. Watch accessories are kinda out in my book, so I dunno how well it'll do in retrospect.
Smartshoes, now that'd be interesting... actually wait, that would totally suck. Smartglasses! Like glasses that don't look lame as hell that have augmented reality stuff AND function like a cellphone and mini computer. They'd really
have to not look lame though... Like Oakleys or something. That, or contacts.
You know, the day when we can have contacts that function like a full fledged computer with augmented reality and such, that'll be the day. Or better yet, eye implants so you won't have to put crap in your eye all the time.
