Zune is a brand from Microsoft that incorporates a line of portable media players, software that will drive the devices, and an online service for acquiring and sharing media. It was previously thought that Zune was one of Microsoft's media players under "Project Argo". However, it now seems that the "Zune" brand will be used for all media players and other services, throughout the new project. The Zune will be released on the U.S. market November 14, 2006, with a price tag of $249.99. The European release date is tentatively set for late 2007 or early 2008.
