Some of the other examples you could maybe say are just poor industrial design or bad execution of a potentially workable idea, but the Intel MBP thermal debacle was definitely the most egregious example of Apple blindly pursuing form-over-function. They set a goal for ultra-slim laptop forms that the components they were using simply could never achieve. It would have been obvious from prototyping that temperature was a major problem, but whatever decision making process they had in place at the time overrode it. The best you can say is they seemed to have learned from their mistake.
