I saw that post, but given the tone, content and veracity of how you criticize apple, its hard to think you're not flip flopping and contradicting yourself quite a bit.
Tim has a great understanding of why Apple is special, he has been there since 1998.
He may have an understanding of Apple and he may not. My point is that you communicated that you came to this realization based on a 4 minute video in which he sat there without uttering a word. To be honest, coming to any realization of someone's grasp of any topic of just sitting there is preposterous.
This is why instructors grade students on how well they interact in class (either verbally or in written form) and they cannot come to a determination that a student understand the material without feedback from that student. Like wise we have Cook who just sits there, but you propose based on that video you realize he gets all of apple's magical qualities.
Plus in prior posts you try to justify your position by saying issues that you have with Apple are not Cook's fault or decisions. But they are, as he's in charge of Apple, don't you think he's the one to give final approval of making a phone thinner, or selling a MBP with a haswell chipset in 2016? You cannot praise him for all the good Apple has done, and not consider him responsible for the mis-steps Apple has also done.
My greatest issue, in light of no real reason for Tim to go, if Tim were to be replaced, I think we would see Apple become destabilised -- that would be worse than any little complaint I or others might have.
I agree to a point, his performance has been steady, but many people expect more from apple, not just more of the same.
Wall street would definitely react negatively, but if they had someone in mind to bring Apple to the next level, it could actually be better. Take Microsoft - Ballmer didn't do a horrible job as CEO, though he was a buffoon in many people's eyes (and he made some significant missteps such as buying Nokia), yet under Nadella MS has improved and flousihed significantly. While Apple is a different company and facing different issues, I use MS to illustrate that changing of a CEO is not always a bad thing.
