I feel that Tim Cook's time as caretaker CEO is done.
He's guided Apple to outstanding profits, but has not shown that he can take Apple to new heights in the long-term. The Apple Watch is not a worthy successor to the Mac, the iPhone and the iPad, in my opinion.
In the five years that he has been CEO, he has never shown the passion for Apple products that Steve Jobs did. As a result, the public has become less enthusiastic also.
Finally, the area that Apple most needs attention is services. Eddy Cue is not the right man to lead this area, to put it mildly. Apple needs a major culture change to instil the right ethos for making high quality services. It goes against their traditional culture in a fundamental way, and requires strong leadership to overcome resistance in Apple. Tim Cook is not able to give this leadership, nor does he have the headhunting chops to find the right person; he is too nice, and doesn't have the sharpness in this field.
It's time for new blood.
