Undortunately, it seems to me that good design requires totalitarianism. Apple's products are comparatively coherent, clean, unified, and aesthetically pleasing. This is achieved via a culture of totalitarianism that extends all the way down to the device. OSX has some openness grandfathered in, but iOS shows you where Apple wants to go.
... and customers largely approve. Having used both iOS and the more open Android, I can say that while Android is more capable iOS is more of a pleasure to use. There you have it.
It's something I have seen broadly in the world, and I actually find it rather disturbing. Bazaars can be creative and can offer a rich array of options and a lot of value, but only a cathedral can deliver aesthetics and usability.
