Today, Microsoft released some official details about the device. One of the main highlighted features will be a song-sharing feature that will enable users to share songs to other close-by users wirelessly. The recipient can then play the song three times over three days before deciding whether to buy it.
Analyst Ted Schadler with Forrester Research said he thinks Microsoft has assembled a strong product with many features Apple's iPod has, and some -- such as the wireless feature -- that it doesn't. Still, he questioned whether music-sharing would be enough of a draw to get people to switch allegiances.
Engadget has a pretty good roundup, including more detailed specs, and more pics, etc.
