What can I do with Bluetooth?

[Rmp5s]

I recently got a LG Fusic from Sprint. I'm new to the world of Bluetooth and I'm wondering what I can do with this thing? I know I can get a wireless headset and I know it'll communicate with some car stereos and stuff, but I know it can do more. I've heard of people syncing their computer with their phone with bluetooth and linking their phone with printers with bluetooth and all...I'm just new to the Bluetooth world and I'd like to get the most out of it. I connected to my girlfriend's samsung A930 with the Bluetooth and my phone said her phone was unsupported. I should be able to send pics and contact info over bluetooth to her phone, shouldn't I? Any info and/or links appreciated. Thanks.

I also discovered something about my computer...it says to setup the bluetooth connection between my phone and the computer, I have to go to start, control panel, printers and other devices, then click on "Bluetooth Devices"...there is no "Bluetooth Devices" thing in that folder...
