Bluetooth

[Kneel B4 Zod]

what do you guys use Bluetooth for?

I have a Treo and my new sweet enV, which both have Bluetooth. I bought a bluetooth headset for the Treo months ago, and I charged it up, but I never really used it b/c the setup was a bit wonky and it kept turning on and off and then the battery died so I said to hell with it.

do any of you guys use Bluetooth for anything useful? I guess the headset idea is cool, but the one I bought is annoying to put on and off and I'm sure as hell not keeping it on.

anything else?
