Honest question: How is Bluetooth insecure? There are some specific insecure devices out there, and Bluetooth has some optional anonymous pairing modes, but my understanding was that the default pairing process provided a reasonable level of security for most applications. Notwithstanding that, I thought Bluetooth LE beacons are broadcast-only, which avoids the pairing issue anyway. And to answer your first question: I leave bluetooth on, both to pair with my car (USB connections don't give enough power to charge with GPS running, and don't provide live audio) and because it's a much lower power way of tethering my other devices to the Internet compared to WiFi tethering. Oh, and my smartwatch uses it too. As does a few other devices at home (BBQ thermometer, conference phone, headphones).
