Apple will be fine post Jobs, people underestimate Cook, he is quieter than Jobs but he is utterly ruthless more so than Jobs was and Apple won't change with him being CEO
Cook has been running the show day to day for years and there has been more complaints about Apple in the Cook era than any other time (lawsuits, Apple suing other companies, the GalaxyII court case, the allegations of using Apple's position to block suppliers from supplying to other tech companies), all that has been under Cook's watch so now he has a free rein Apple will crush the market even more so.
