S. Jobs injected his DNA into Apple. They are setting up the Apple university, they are building the new billion dollar Apple campus. Apple is the largest tech company on the planet and they have close to $100 billion in cash. They could scew up for the next 20 years and still be around. However, most likely they are entering a new phase in the lifetime of a corporation.
And i have commented on why that, while of course good, may not be enough to keep progressing. As for being around, i never think i stated otherwise. Being relevant, and being around is two different stories though.
...Not that i doubt that Apple will be relevant for the foreseeable future either, though. Just trying to add some perspective here.

Why? You don't think they have a roadmap for new products at least 4 years out? Th iPad and iphone were both in development more than 4 years when they launched. Apple's major plans are rarely impacted by the rest of the industry. Over the past 5 years in computers/mobile Apple has driven nearly all the change.
I believe Apple's only design close to 8 years old is the classic, there is some debat if they even manufacturer it still.
I call bullcrap. Apple is in every way dependent on the developments in its environment. Others enabled the success of Apple; consequently, "even the plans of Apple" are in every way impacted by the rest of the industry.
