Dell has stopped selling Apple’s popular iPod MP3 player because of changes Apple wants to implement in its reseller agreement. “We have already stopped selling the iPod — the old reseller agreement ended on March 31, 2003 and all SKUs have been turned off,” Mary Fad, a spokesperson for Dell, told MacCentral. Fad said Dell refused to sign a new reseller contract proposed by Apple, and that it no longer had any iPods in stock. We reported in October of last year that Dell had started selling the Windows version of the iPod.
