Palm might have tried a strategy of continuous innovation but it is difficult to continue to advance technology, especially when you are dependent on infrastructure that is capital intensive like communications networks.

But your point is absolutely spot on and well taken. I watched upper management absolutely destroy several companies over a period of 25 years by a succession of strategic blunders that were almost remarkable in their scope. What caused them? Groupthink, and the primacy of company politics and inward looking bias.
