The Zune XD is Microsoft's flagship touchscreen mp3 player. It was launched in 2009, after the successful 2008 launch of the Zune HD, designed to compete with Apple's iPod Touch device. The Zune XD has a 854x480 4" screen, and comes in 32GB or 64GB memory sizes. As of December 2009, there are 590 apps available for the Zune XD, including a version of Final Fantasy, Marvel Ultimate Alliance, Battleship, Doom, Quake, and several other popular franchises. Apps include Youtube, RSS reader, Facebook, Calendar, Contacts, and Twitter. For January, Microsoft announced that another 120 apps would be forthcoming on the Zune XD platform, most of which will be coming from 3rd party developers, and independent app developers who went through the app store process beginning in November.
