You claim to have knowledge of the "business world" but don't realize it was Tim Cook's expertise in chain management that made Apple utilize a number of suppliers like Sharp, LG, Samsung instead of one supplier. His streamlining process saved Apple billions in efficiency not to mention not having to bend their butt for one supplier by having many suppliers they can go to if they were to get shafted by their main supplier.
You view Tim Cook through the eyes of an Apple fan (which is who Steve Jobs catered to) but not through the eyes of a businessman.
I never claimed to have knowledge of the "business world." Show me where I said that. I am just stating what I believe and what others also believe regarding Time Cook. Being a businessman does not equate to being a technology man.
I am not doubting Tim Cook's expertise in chain management. What I am doubting is his ability to be innovative with new technology and products. He can be the best chain management expert in the world, but if he can't help design new products and provide Apple's next 5-10 years of product development that will all be for naught.
