Oh, I'm mostly worried about "dragnet" approaches and script kiddies. I still occasionally use a wireless keyboard to type in a password, but by avoiding these, I also lower the probability of interception. It makes me most uncomfortable when I am typing log-in credentials to my personal home server, that could be used to log in over the internet. Other than that, I work at a lab, which sounds like a juicy target for leaving a passive Bluetooth sniffer in a closet somewhere. I've just played enough with BackTrack (now Kali Linux) in my teens to know that other people may be doing the same.
