http://www.apple.com/mpeg4/aac/ Does this mean that iPod MP4 Players could be on the way? I CERTAINLY HOPE SO!!! MP4 Players could bring the same audio quality that MP3 gave us, but at a much lower bit rate, boosting the overall number of songs we can store on our portable players. Or it could be used to maximize the sound quality of our music by giving us higher quality sound (than MP3), but at the same or higher bit rates resulting in true Dolby Digital/THX/Surround Sound!!! Neato!
