Bluetooth wireless technology is a short-range communications technology that replaces the cables connecting portable devices and fixed devices while keeping high levels of security. The big features of Bluetooth technology are easiness, little battery power, and low cost. The Bluetooth specification defines a uniform structure for a wide range of devices to connect and communicate with each other. Bluetooth wireless technology is the simple choice for convenient, wire-free, short-range communication between devices. It is a globally available standard that wirelessly connects mobile phones, portable computers, cars, stereo headsets, MP3 players, and more. Thanks to the unique concept of "profiles," Bluetooth enabled products do not need to install driver software. The technology is now available in its fourth version of the specification and continues to develop, building on its inherent strengths — small-form factor radio, low power, low cost, built-in security, ease-of-use, and ad hoc networking abilities. Bluetooth wireless technology is the leading and only proven short-range wireless technology on the market today with an installed base of over 1 billion units at the end of 2006.

Here is the range specifications
The operating range depends on the device class:

Reaction: I think that bluetooth is a better and higher piece of technology that will be used for a very long time, it is easy to use, and has no wires attached, so its portable and convenient!
