The Zune is a portable digital media player from Microsoft . The first version, released in November of 2006, is about the size of a deck of playing cards and weighs 5.6 ounces.
To meet the power demands of the 3-inch LCD color display and, on some models, integrated WiFi ( 802.11g ), the Zune uses a lithium-ion battery . This screen is capable of playing videos and movies that have been uploaded from a PC to the internal 30 GB hard drive. Video content may be viewed in either a horizontal or vertical orientation. A static, five-way directional pad provides internal navigation. The Zune connects to a computer with a proprietary external USB cord, allowing users to create playlists, synchronize files and purchase music from Microsoft's Zune Marketplace. The WiFi connection, however, cannot be used to synchronize with a PC, purchase content or access the Intenet. Users can stream purchased music from a Zune to Microsoft's Xbox 360.
The Zune player supports various file formats, including . WMA , . MP3 , . AAC , . JPEG and . WMV . Unlike the iPod , the first-generation Zune does not support podcast s, function as an external hard drive or work with Apple 's OS X . It does, however, feature an FM radio and, on WiFi-enabled devices, a wireless sharing functionality, called "Zune to Zune." Encoded DRM (digital rights management) restricts exchanged files so that the recipient can play them no more than three times in three days.
