From being close to someone who worked there for many years, from the iPod-is-just-new til a few years ago, I'd say actually this culture at Apple is a product of the return-of-Steve-we're-barely-surviving Apple-austerity mode. I don't know how engineers do there, but the marketing people I knew from there worked like dogs but when the money started to rain from the iPod/iPhone/iPad sky, I didn't get the impression that they really benefited from that.
I work at Google now, there is plenty of money coming into this company and hard workers (and not-hard workers) are getting a large share of that. And while it isn't a complete paradise, the company seems grateful to its workers. I can't say I got that impression from anybody I know who worked at Apple or was close to people who did.
