I have heard conflicting reports as to whether or not there is a succession plan in Apple should Jobs leave be permanent. Whether you like Apple or not, this guy has had such a huge influence on the world we live in that it's really hard to imagine him NOT being arround.
Ars Technica has a pretty funny article (well... funny under the circumstances) regarding the "sky is falling" mentality of some of the technology pundits who are on the verge of proclaiming the end of Apple.
My favorite section of the article follows (italicizes NOT mine):
Worse yet, we're told that Jobs might be holding back critical information, and that it may be in an effort to defraud investors. And the SEC might investigate, especially if investors maybe sue if there's a big stock decline. I haven't seen that many conditional statements since I last translated Philo of Alexandria.
Today's Bloomberg shocker: Tim Cook, the Chief Operating Officer of Apple, has actually been running the company for years. Instead of, you know, making cakes or grilling tofu burgers, or whatever it is that a COO who isn't being a COO does. Next they are going to reveal that the company's CFO has been overseeing the financial health of AAPL for years, quietly.
