A person like Steve Jobs comes along only once per century. He had incredible vision and knew how to execute. As for choosing his replacements, he has proven that he is not good at that. A good bet right now is to short Apple stock.
You do know that Tim Cook was basically the CEO for many years before Steve passed away. Most of the company reported to him and he is one of the major reasons Apple is alive today. Also he is the ONLY one who is respected enough and capable enough to manage the team of egos Jobs cultivated.
So go ahead short the stock. Will be hilarious to watch you lose money if the iPad Mini and AppleTV rumors are revealed to be true.
