The MusicGremlin, a portable Wi-Fi music player, uses a direct wireless link to a music store to cut out the middleman–your PC–from the music-gathering equation. A $14.99 monthly fee lets you grab all the music you want–or, at least, all that will fit on the 8GB MusicGremlin device–from the MusicGremlin Direct online store. Clever community features let you browse other Gremlin owners’ downloads and swap songs with friends.
