The new MusicGremlin Wi-Fi media player allows access to 2 million tracks which you can download without the use of a PC. ‘Finally a media player that takes full advantage of wireless technology. The MusicGremlin challenges the iPod (and yes the Zune) with the only computer-free, wireless download technology of its kind. Connect the Gremlin to any 802.11 Wi-Fi network and browse or download any of over 2 million tracks directly from the device... no PC needed. You can even share songs with other MusicGremlin users anywhere in the world.’
