ashinsky: I think Apple will change. It will have to change if for no other reason than because it is so much bigger and so much more complex than it was 15 years ago when Steve Jobs came back to the company that he had co-founded. Should it change? Sure. They will have to adapt to a new reality of being big, of having more scrutiny. For example, their secrecy will become more and more difficult over time, and I suspect they will try an intelligent approach to adapting to that difficulty rather than just trying to hold things off as long as possible.

Knowledge@Wharton: We'll come back in a bit to the issue of secrecy about which I have a few questions. But for now, why don't we talk about Tim Cook and his leadership style? Do you have a sense of how Cook is putting his stamp on Apple and how he should, in some ways, think differently by not emulating Jobs in everything he does?

Lashinsky: One thing that Cook has going for him is that he is not Steve Jobs, and my impression of the man is that he is not confused at all about this. He is extremely different from Jobs in almost every way. He is not an emotional person. He doesn't have a creative or artistic background the way Jobs did. He's passionate about Apple, he's passionate about business, he's passionate about operational excellence. I think eventually he will put his stamp on Apple, in that it will be more professional,
