Rene Ritchie of iMore notes that contrary to Craig Hockenberry’s observations, outside hires have been made at Apple, and they turned out pretty okay:
Phil Schiller came to Apple from Macromedia, a company whose kludgy interfaces, customer-hostility, and software DRM is antithetical to Apple’s entire approach. Tim Cook came to Apple from Compaq, a company whose uninspired, beige-box take on personal computing is the opposite of the delight Apple strives to instill. Yet both Schiller and Cook merged brilliantly with Apple’s culture, and now enjoy the very highest positions within the company. They were home runs. They’re stars.
