Windows Phone Thoughts: Bluetooth 4.0 Standard Finalized

"Bluetooth low energy and its predecessors (think Wibree) have been in the pipe for ages now, but we might actually see this tech take off en masse for the first time now that the Bluetooth SIG has officially added it into a release: 4.0. While Bluetooth 3.0 was all about high energy with the introduction of WiFi transfer, 4.0 takes things down a notch by certifying single-mode low energy devices in addition to dual-mode devices that incorporate both the low energy side of the spec plus either 2.1+EDR or 3.0."

Beyond Bluetooth headsets, and in some cases stereo headphones, I just don't see much in the way of Bluetooth devices. I know that is all the average consumer thinks of when they hear Bluetooth. I know that BT 3.0 specs were released a while back, but i couldn't name a single 3.0 device. Heck, I don't even know if my phone is 2.x or not. It works with my headset, that is all I care about. Any of you have a BT 3.0 device?
