Since its launch, the iPod has gained fans from Downing Street to Hollywood and has spawned an industry of more than 4,000 accessories - including a Louis Vuitton designer case. Despite a brief dip last year, sales have picked up. In the three months to December, Apple delivered 21m players - an increase of 50% on the previous year's run-up to Christmas.
Credit for the iPod lies partly in British hands - it was designed by Chingford-born Jonathan Ive, who is now Apple's head of industrial design.
