I'm looking for some kind of small Bluetooth device that doesn't do anything but be discoverable. I know these things exist, but I don't know where to get them. Basically, I want something small that I can carry with me so my computer will do the auto away stuff. Some people have suggested a bluetooth phone, but I already have a phone, don't want a different one. The best suggestion I've had was that I get a bluetooth earpiece. Anyone else have any ideas?
