Phones in Heads

I was just thinking that it seems like people could do this right now if they wanted to. It's the next logical extension from the bluetooth headset. Get a cell phone implanted right under their skin, near their temple lets say, and using the sound transmission properties of the skull, it could speak the phone number calling you, or whatever and no one could hear it. This might be a drawback though: how would you see anything? Perhaps the cell phone is still present so you can see the numbers to dial and this is just a headset implant. The battery life could be really long, and it could be recharged through induction just like my electric toothbrush is today.

Ok so I'll admit it, this is a pretty creepy idea, bordering on the "not good" ideas that I keep from sharing (the ones that I think would be not good for the world), but also how can humanity resist something like this? Once you start getting phones in heads it borders on telepathy and people always want psychic skills, or at least they say they do. You touch your head and communicate with your friends. Do it right, and the numbers go away, replaced with voice command names. It's crazy how doable all this is now. reading a christensen book on disruptive innovations in education. This would be a disruptive innovation in communication - lots of factors that are currently valued in cell phones (nice screen, web, cool features) would have to go away, but whole new applications would be enabled.
