"Support for Bluetooth Wireless
          Technology is not in the first release of Windows XP, because there is
          not a sufficient array of production-quality devices that conform to
          the Bluetooth Specification for Microsoft to test. However, Microsoft
          is actively developing support for Bluetooth Technology and will ship
          this support in a future release."
