I have not used Microsoft’s Zune but based on its features I can say that I never would buy or recommend one.

One of the worst things I have ever heard: if you create your own music (for which you obviously own the copyright) and then share it using the Zune’s wifi, the Zune will add DRM (digital rights managements software) so that the recipient can’t do anything with it except play it on their Zune. In other words, Microsoft has taken over your distribution rights for that copy.

While adding wifi is a good feature the Zune doesn’t make it available for what you want it for (synching, catching streams, or downloading) only a very limited form of sharing (the lesser of 3 plays or 3 days) so that they can try to get people to buy the song from their store.
