I've worked at a lot of places. I've been told that open-heart surgery would be counted as a vacation day. I've been in 3-hour meetings where a dozen executives bickered the whole time over how one toggle should be labeled. I've been where fully half the employees had been fired and continued working on the sheer grace/need of the owner. I've been given hard deadlines to complete hundreds of pages of documentation nobody would ever read. Etc...and plenty of people on HN have their own equivalent stories. Apple is a big company, and can't keep everything pristine and orderly, and still has to meet massive big-budget deadlines by every means necessary.
The kicker: Apple gets results. One way or another, that system works; one company does not have one product take over fully half of an entire major electronics market unless they're doing something right.
