Bluetooth and security
While driving around yesterday I listened to the Kim Komando Show on the radio. She said that thieves are using Bluetooth scanners to locate portable devices (tablets, laptops, etc.) hidden in cars in order to find something worthwhile to break in and steal. She implied that the device didn't have to be in BT's "discoverable" mode, and suggested that such devices be turned off completely before leaving the car.
And here I was, thinking Bluetooth wasn't good for anything.
