According to Chris Stephenson, Microsoft General Manager of Marketing for the MSN Entertainment Business, Zune is an umbrella brand for what he says is "a family of hardware and software products" targeting various digital entertainment services.
The first implementation of this will be the portable music player and digital music service.
Additional Zune-branded devices will follow, including a portable video player and, potentially, a portable game device, although Stephenson would not comment on the videogame element of the initiative.
At the same time, a lot of companies have developed some products for Zune.
Now I'll list some key differences between Zune and ipod.
Zune support MP3,Zune Marketplace(Protected),AAC,WMA,JPEG(Photos),WMV(Videos),MPEG-4(Videos),H.264(Video).
IPod support iTunes(Protected),AAC,AIFF,WAV(Uncompressed),.aa,JPEG(Photos),BMP(Photos),MPEG-4(Videos),H.264(Video).
FM Radio:
Zune has a built-in FM tuner. But if you want to listen to radio on iPod, you have to buy an accessory.
Battery:
The battery Life of Zune is reported to be up to 13 hours, when listening to music with the wireless turned on. With the wireless off, battery life is up to 14 hours and up to approximately 4 hours for video or pictures, all of which is similar to earlier rumors and informal comments. However, some folks think the testing conditions are wildly unrealistic.
By comparison, Apple's 30GB iPod is rated at 14/4 hours (music/video) and the 80GB iPod at 20/6 hours.
You can find other differences from the illustrations I posted or more iPod and Zune comparison information.
