-"Bluetooth is a technical industry standard that facilitates communication between wireless devices such as mobile phones, PDAs (personal digital assistants) and handheld computers, and wireless enabled laptop or desktop computers and peripherals.
-A single Bluetooth-enabled wireless device is capable of making phone calls, synchronizing data with desktop computers, sending and receiving faxes, and printing documents."
-When you see people talking to themselves while walking down the street with little blue lights flashing near their ears, it's because they're utilizing a Bluetooth earpiece that is communicating wirelessly with a cell phone.
