Apple sweats the details, but overall they're very selective about which details to sweat, to the exclusion of all else.

They're realistic about the fact that you need to ship, and that if you want to both sweat the details and ship, you've gotta focus on a few core features, and either nix all the others, or put them on the roadmap for future builds/patches/expansions.

Seems to be the best of both worlds so far.
