Switcheasy has launched ThumbTacks, an ultra-small microphone for the iPod nano 4G and iPod touch 2G. The microphone attaches to the iPods's 3.5mm headphone jack and allows the media player to be used as a voice recorder. The ThumbTacks microphone is shaped like a thumbtack and measures 1.21 inches by .46 inches, using gold plating on the plug.
