The celestial jukebox is finally headed to your pocket. Maybe. MusicGremlin recently introduced the first Wi-Fi–equipped MP3 player. The 8GB model, which is available at www.musicgremlin.com, uses a built-in 802.11b connection to let you wirelessly sync tracks from your PC, beam songs to other MusicGremlin players, and access online subscription services.

And it’s possible that MusicGremlin will prove to be only the beginning. Microsoft is rumored to have in the works a wireless media player called Zune that may support free conversion of some or all of the audio tracks you purchased at the Apple iTunes Music Store.

If Microsoft pulls off a nice Wi-Fi–enabled design, we’ll really have something. The MusicGremlin is a cool idea, but its current player is too chunky to take off .
