If there is one racing certainty in the world of technology, it is that sometime this year Apple will announce that it has sold its 100 millionth iPod. Indeed, by December 2006, a little more than five years after its launch, there were already 88m of the fashionable little personal music players in use.

Perhaps what is equally surprising is that more than half of those iPods are being used to watch videos and read documents as well as listen to the latest hit song, according to Pascal Cagni, vice-president and general manager for Apple in Europe, the Middle East and Africa. All of which presents a dilemma and an opportunity for business schools: how can they use the power of the latest sound and video technology to improve the learning process?
