boynq has an interesting new USB VoIP product called Notone. It's a mono PC speaker with a VoIP handset receiver and 3M quick note papers (PostIt Notes), as well as a pen holder. It features a small microphone to allow for handsfree talking or you can simply lift up the handset and it will automatically override the main speaker and microphone to its own speaker and microphone to make a private call. They even added a USB port extension on the side, which means it's a net zero gain/loss in available USB ports.
