We now have a few more details on Microsoft's Zune portable-media players than we did yesterday. The first Zune model, a 30GB player with a three-inch screen due out some time this holiday season, will feature Zune-to-Zune wireless connectivity for sharing full-length sample tracks of select songs, homemade recordings, playlists or pictures. The devices will come in black, white or brown. Peripheral vendors are working on all kinds of add-ons. From the start, there will be a car pack, A/V pack (for TV connectivity) and a travel pack. No word yet on official pricing, however.
