I'm curious to know what people think of this question. There are two aspects to Jobs : 1) role as traditional CEO 2) charismatic leader who guides the creativity of the company The first part makes this a complicated question. I feel Apple would not survive if # 2 isn't satisfied. Based on that, I'm claiming Jonathan Ives will be his replacement. If you notice the patent applications, he and Steve Jobs are listed together quite often. What do you think?
