Apple CFO Peter Oppenheimer has revealed that Apple's iPod shuffle now has a 58 per cent share of the flash-based digital media market in the US.

This is up from a 43 per cent share in February, as revealed by Oppenheimer in Apple's second-quarter financial results conference call with analysts. The figures are from market research firm NPD.

Oppenheimer is positive that the flash-player market share will continue to grow. He told Merrill Lynch analyst Steven Milunovich that Apple was "supply-constrained in March" hinting that the figures for April will be even better, writes The Mac Observer.

No competition

Apple's CFO also claimed that "Apple isn't feeling the competitive heat yet" in the digital media device market.

According to Apple's own figures, Apple boasts a 90 per cent share of the hard disk-based MP3 player market and 70 per cent of the digital music download market.

Mobile moves

Oppenheimer also insisted that Apple "doesn’t appear concerned" about the threat from music-playing mobile phones. He told Milunovich that MP3 capability in handsets will be more complementary than a replacement. "The negatives of music on a handset include a worse user interface and limited battery life," he told Milunovich.

Nor does Oppenheimer foresee any problems working with the mobile phone operators, despite suggestions that the carriers are unhappy with what the iTunes enabled Motorola mobile phone will offer them.

Milunovich expects Apple to reveal iPods with wireless and video capacity before Christmas, he also claims that the US may see more Mac advertisements on TV.
