Microsoft will be watching events in San Francisco tomorrow very closely as Apple and Motorola unveil the iTunes mobile phone. Indeed, the software giant is already planning to move into that space as well.

In the international business press, Microsoft spokesman Jason Langridge said: “The mobile digital music market is about to take off. Porting digital music on to mobile phones represents a massive opportunity for Microsoft. While Apple has sold about 10 million iPods worldwide to date, a quarter of the world’s population own mobile phones, which Microsoft software can turn into digital music players”.
