The Bluetooth SIG, overseer of the wireless communications standard, was quick this morning to state that Apple's iPad 3 "is the world’s first Bluetooth Smart Ready tablet, incorporating Bluetooth 4.0 and its hallmark feature low energy technology".

The SIG didn't say as much, but this is no surprise since not only the iPhone 4S but also the latest MacBook Airs support Bluetooth 4.0 too.

But what the heck actually is Bluetooth 4.0, and why might it matter?

According to the SIG, "as a Bluetooth Smart Ready hub, the new iPad is ready to connect to the expanding universe of Bluetooth devices" including "new Bluetooth Smart devices: fitness sensors like the Polar H7 or Wahoo Blue Heart Rate Monitors, Casio G-Shock GB-6900 Smart Watch, etc.".
