I think if he left 2 years ago, it would have been a massive deal, and sent Apple stock crashing down. Now.....not so much.
Popularity always reaches a peak. For Steve Jobs, that peak was 1-2 years ago. If Steve leaves in 1 or 2 years, Apple will be OK.
Regard the Gizmodo article, it's very possible that the Board of Directors and SJ sat down and discussed his public image, which
was Apple. That's great for the ego, but not for the company, because, as you feared, if Steve is Apple, and Steve leaves, Apple's stock, reputation, etc, are gone with him. That may be the reason why Steve doesn't make himself the star anymore. It may not be health related whatsoever.
Even if the company would be able to operate well without him, the public perception would hurt Apple a lot financially. They'd be like Ford or GM, who have improved greatly, but still have a negative stigma regardless of how much they improve.
Anyway, I'm kind of looking forward to Steve leaving Apple.
