Adam Lashinsky, Sr. of Fortune takes an interesting look at Tim Cook and how the new CEO is changing Apple. He spends a great deal of time writing about Cook's business practices and the philosophy that'll shape the Apple of the future. Lashinsky writes,

In general, Apple has become slightly more open and considerably more corporate. In some cases Cook is taking action that Apple sorely needed and employees badly wanted. It's almost as if he is working his way through a to-do list of long-overdue repairs the previous occupant (Jobs) refused to address for no reason other than obstinacy.

He also talks about Cook's relationship with Apple employees and presents Cook as a much more approachable leader than Steve Jobs who was "simultaneously revered, loved, and feared." You can read the entire article on Fortune's website.
