While plenty of iPod owners sit and dream about being able to download songs from the iTunes store straight to their 'pods, a new music player has come out that does just that sort of thing. The MusicGremlin ($300) uses built-in Wi-Fi to download from its store of over two million tracks. You can either buy them one by one for 99 cents, or sign up for a $15 monthly subscription plan and download until the 8GB player is full. As an added bonus, you can actually wirelessly swap tracks and playlists with other Gremlin owners, provided they are on the subscription plan as well. Add a built-in FM radio, and you have one heck of a challenger to the iPod. Let the games begin.
