Air features Bluetooth 2.1 + EDR

Not a bad turnaround time -- Bluetooth 2.1 + EDR, ratified just a few months back by the Bluetooth SIG, has found its way into the MacBook Air's unnaturally thin shell. This should lead to improved (read: quicker) pairing, better battery life, and improved security over 2.0. Only trick is to find a few other 2.1 devices, of course.
