Apple is a user experience-centric culture, with a profound appreciation for how excellent engineering makes better user experiences possible. This definitely doesn't strike me as hacker-centric in that Googley/Facebookey way that PG describes. Apple undoubtedly employs many talented hackers, but they're not so much the center of its culture as they are its foundation. A brilliant and responsive UI with a stupidly simple implementation will be more highly prized than a work of coding genius that only marginally furthers user experience.

Of course, if you want to extend the idea of hacking so that one can speak of user experience hackers, then Apple would definitely qualify as having a "hacker-centric culture".
