Apple to Quit Macworld Expo

Apple shocked observers by announcing yesterday that its appearance at next month's Macworld Expo will be its last, Marketwatch reports. CEO Steve Jobs will not be giving a final keynote address at the San Francisco industry gathering where he has traditionally unveiled new products. The company's stock dived 5% following the news amid rumors about its significance.

A statement from Apple said trade shows have never been a big part of its business. Some experts speculated that the move could mean Jobs' health is failing, however, or that an internal power play is afoot. "Apple could have dismissed a lot of rumors by having him give the final keynote and opted not to," said an analyst. (More Macworld stories.)
