This is awesome. I still remember the slow push from 1.1 to 2.0+ took a little while and now they have been pushing Bluetooth upgrades forward at a quick pace. If only Wi-Fi standards could do the same. Might be time to upgrade my Bluetooth 1.1 headset.
Looking forward to higher transfer rates and such alongside the 3 modes, it would be pretty epic for a lot of devices to have it inbuilt just to transfer small files, even HDD's. You wouldn't think about the amount of times I had to stay rummaging through my bag to find the cursed USB cable just to upload a document to it from my laptop when it could be so much better if they just implement a small battery (like that used for the CMOS and Watches) to let you do just that through wireless connection. Extra brownie points if the battery recharges while the device is plugged in via USB.
