There might be a new Sony Walkman in the near future that will appear at retail stores near you – the E440. What makes this different from the rest is this – it comes with a pair of built-in speakers located on both top and bottom of the display, making it slightly longer than its predecessors. Bold colors look set to be used in the Sony Walkman E440, while retaining the Mickey Mouse controls that are found in its predecessor. This will most probably be useful for those who love to share their music with everyone else on the train or bus, whether the others are willing to hear Britney Spears or not is another matter to consider.
