Microsoft Zune is a shot across iPod's bow. By tightly integrating the Zune device with the Zune online store, Microsoft has made a digital audio player that is nearly as easy to use as the iPod. It has even added some innovative features, like the ability to share songs and pictures with other Zune users via WiFi. The device with elegant interface, three-inch screen, built-in Wi-Fi and photo sharing with other Zunes is a good iPod alternative.
