TechCrunch reviews the Microsoft Zune

John Biggs talks about the Zune here

The Zune has 802.11 networking built in and you can send a song to your friend for three days or three plays, which ever comes first. The goal, obviously, is to sell music. However, we could also conceivably see this as a MySpace-like network of users who pop music to each other with giddy abandon and infect others with their musical stylings on the train (perhaps a sandwich board that says “I’ll Send My New HARDCORE RAP Single to Your Zune. Talk to me. Please?”) Once you get back home you can connect to the Zune Marketplace – and presumably an artists home page – where you can learn more and buy music.
