Yeah, what he said. A Bluetooth bone conducting headset in a tooth… That would rock!
All Book of Revelation and Book of Orwell and such aside, does anybody really want to install a bit of electronics in their jaw that only has 512MB of memory, Bluetooth-enabled or otherwise? The dDrive is a concept from industrial design firm Creganna that would be designed to store medical records, security clearances, etc., and while I don't have a huge problem with that in and of itself, I don't think I'll be giving up one of my teeth just for something that's going to be obsolete in a year. At least not just for storage - get a Bluetooth-enabled cellphone headset in there and we'll talk about it.
