I also had the white-stuff + light-gun fillings some months ago. Liked it, as one filling was a tooth near the front and it doesn't make it look darker than the adjacent teeth.
My folks bought a new car recently, and it had BlueTooth integrated into the sound system (but maybe I'm behind the times being impressed by that). My father also recently got hearing aids, and they also have built-in BlueTooth! (Maybe next people can get implants and we'll all have "native" BlueTooth.) And each hearing aid apparently "talks" to the other in some wireless fashion. I wanted to dig in and read up on the specs, but he didn't have the manual (argh).
