Apple jumps out in front, as is typical, and adds Bluetooth 2.0 to its laptops: The entire PowerBook line of laptops will include both AirPort Extreme (802.11g) and Bluetooth 2.0, which adds a 3 Mbps flavor to Bluetooth that an Apple executive told me in an interview today should make it possible for the highest-quality music streaming to Bluetooth headphones among other devices that they expect will incorporate the new technology. This new flavor of Bluetooth is called Enhanced Data Rate (EDR).
Apple says it's the first to add Bluetooth 2.0, and at first glance that seems correct. It's easier for Apple to change the plumbing to add specific hardware to their monolithic operating system than, for instance, for Microsoft to suddenly support 100 different manufacturers' flavors of Bluetooth 2.0. This lets Apple be strangely nimble.
The underlying chips appear to be from CSR, which had the first certified 2.0 chips late last year. CSR will integrate this technology into a new Bluetooth optional card for Dell laptops, the TrueMobile 350 Module. The 300, currently sold as an add-on, supports up to Bluetooth 1.2.
