Hi SpadesFlush,
With respect to the original post, Tao is exactly correct. The device described in the Microsoft promotional material is not a Bluetooth device.
It's good to know that you can buy a Bluetooth dock for it, but as you say, the dock looks to be as expensive as a Bluetooth receiver.
JohnnyK,
It's worth knowing that the promotional material you quoted was written by some ***** (Hey Marvin, why is i-d-i-o-t in the censored words list??) in Microsoft's marketing department who has likely never used a GPS.
It's really not very useful, in most situtions, to be able to plug the GPS receiver directly into the laptop USB port. That is usually about the worst possible place to locate the receiver. The receiver really needs to be located somewhere that gives it as unobstructed a view of the sky as possible. In a vehicle that's as far forward on the dash as you can get it. In a hotel room that's over on a window sill as close to the window as you can get it.
You can often save enough money by buying the software-only version of Streets&Trips to buy a Bluetooth receiver. As SpadesFlush and Tao said, that's the best way to go.
