Simple answer: The change is a cargo cult. They see how Apple does this with their products and keep increasing uptake. They don't know that it isn't only the visible change itself that motivates adoption. Apple is keenly aware. Apple's customer isn't the person using Apple's product--that person can be inconvenienced (plus they tend to self-brainwash). The real Apple customer is the person watching an affluent/influential person using an Apple product and imagining how nice it must be based on the (superficial) clean simplicity of it all.
