I've loved and used Apple computers for years, but I am totally new to this new Bluetooth technology.

Now that I have this cool new iBook, I'm wondering what other things I can do besides hook up to wireless internet almost everywhere I go.

I am about to purchase a cell phone with a Bluetooth headset, too. I suspect I could have the computer "talk" to the phone when a cell phone signal is available and a wireless internet connection isn't available to set up a cell phone based wireless signal (instead of using a cable from the phone to the computer), but are there other uses for this Bluetooth stuff?
