Dell <A HREF="http://www.statesman.com/business/content/business/stories/technology/02/4dell.html">discontinued three Digital Jukebox players</A> that sell for $200 to $300 in late December and early January, but will still sell the $99 DJ Ditty. The decision underscores the difficulty companies including Dell have had trying to unseat the best-selling iPod. Dell introduced the music players in 2003 as part of a strategy to expand sales beyond desktop PCs. The versions being scrapped used hard drives to store music; newer models use cheaper flash-memory chips.
