Logitech early Tuesday morning brought out the Harmony Link, an adapter focused on turning the iPad into a true multi-role remote. The puck-sized hub bridges a Wi-Fi link to infrared and, through an app, lets the iPad handle everything a Harmony remote could, including macro-based tasks like playing a movie or listening to a home stereo. Viewers also get a customized program guide through Rovi to help match the TV's own guide.
