The laptop I'm using with us is just "old enough" not to have built-in Bluetooth, so this adapter serves a dual purpose: (1) it allows me to use a Bluetooth keyboard for incoming traffic (which fits in an accessory bag) and (2) it also allows me to play digital music over "stereo" without a connecting cable. The compact size also means I don't have to unplug it from the USB port when I put the laptop in my carrying case. The only thing that took some getting used to was the blinking to confirm the connection. A minor inconvenience given what this does NOT do for me.
