Apple's growth hinges on China, new devices - Chicago Tribune (click for full article) "SAN FRANCISCO (Reuters) - Sometimes even eye-popping results are not enough. Apple Inc's shares rallied on Wednesday on the back of another spectacular quarter that included soaring iPhone sales in China, but the naysayers are still asking if the most valuable American company might need yet another revolutionary product in the next year to sustain its sizzling growth. The skeptics certainly lost some credibility when the company's shares surged 9 percent on Wednesday, adding about $50 billion to Apple's market value, but some have not been silenced. Their case is based on the law of large numbers - it is going to be more difficult for Apple to grow as fast the bigger it gets - and on the unforgiving nature of the technology business that can turn heroes into has-beens overnight. The bulls point to emerging markets - in particular China, whose mobile market is the world's largest and far from saturation - and upcoming products like a 4G-enabled iPhone 5 and the oft-rumored Apple TV, as sustaining astonishing growth such as the near-doubling of net income in its second quarter. But the bears, with a longer-term view, fear that Google Android devices will eventually put pressure on Apple's margins in China as they have elsewhere, and wonder if Apple will be successful in tacking on another blockbuster consumer device to its portfolio.

In products, "TV seems to be one that everybody is looking at," she added. "
