The Zuuuuune. The new gadget of the end of the year will use peer-to-peer. Why and by what should people replace my iPod? Because people want to share their music. Zune will offer the feature to share the music stored on your mobile device for 3 days and 3 times to listen, after which they can flag the song for purchase on the Zune Marketplace. Zune-to-Zune sharing is where the real action! Legal file-sharing is possible!
