Financial publication Fast Company has published a new ranking of possible replacements for Apple CEO Steve Jobs. The magazine notes that even if Jobs does return from his current medical leave, the company will eventually have to find a replacement. The top potential candidate is argued to be Apple's senior VP of iPhone software, Scott Forstall. He is "young, possesses the right kind of technical knowledge and dynamism, and has become an increasingly important figure in key Apple product decisions," according to the magazine.
