For a failed technology, it's looking pretty good: Weekly unit shipments are 12m in devices; in 2010, they have a goal of shipping two billion units--in that year. Bluetooth 2.0+EDR solved a lot of frustration with throughput, range, and co-existance, making a better audio experience possible. The future of Bluetooth is now tied to UWB, and it's a year until we'll see the fruits of that collaboration. With Bluetooth over UWB, the same applications will be available with little effort on the part of developers to make them work with a different radio set.
