Our boys at OCAddiction look at the Belkin Bluetooth USB Adapter, PC Card and
PDA Adaptor. If it's from them, it's a good read. Check it out here.
The Bluetooth USB Adapter adds Bluetooth technology to your
existing USB PC or notebook to let it work with all devices enabled with Bluetooth
v1.1 technology. Wirelessly print, synchronize your PDA information, and create
dial-up connections through a mobile phone. From up to 100 meters away you can
effortlessly transfer data to other Bluetooth devices such as desktop or notebook
computers, PDAs, scanners, printers, and even mobile phones-wirelessly. Connect
with up to seven other Bluetooth devices at a time.
