Kensington have created a micro Bluetooth module that connects via USB, adding Bluetooth functionality to any machine.
The thing that sets this appart from other Bluetooth dongles is clearly its tiny size. I constantly find that having USB drives hanging out the side or back of my laptop is a great way to get one of them snapped off.
Being so small, you could comfortably leave this always plugged into your lappy without the fear of having it snapped off. A great design.
