Not to mention that the on-the-go playlist feature worked great on iPods (just hold the button down) but Apple still hasn't figured that out on iPhones.

Agree that Bluetooth is a nightmare. Every Bluetooth radio wants to dig into my phone and download my contacts (and who knows what else) but all I want to do is play music. If I do this in a rental car I have to remember to figure out how to wipe the radio when I'm returning the car and already rushing to catch a plane, so I don't even bother with Bluetooth any more. It's maddening.
