> Not a good advice for any public place (airports, cafes, etc). Very easy to listen to BT and intercept passwords as user types them in.

It's worth the risk to get people to use a iPhone or iPad more routinely. Also, the risk of this is exceedingly low because an attacker needs to actively interfere with the pairing process and be physically present for collection. This attack doesn't scale like "It's Windows, go pull the hard drive and read everything on it." I've never heard of LE using active BT attacks and I keep up on these things.
