[Apple] keeps its product line focused, and meticulously refines it year after year, making everything a little bit better. Which means by four or five generations in, especially when it comes to industrial design, Apple’s products tend to hit a sweet spot, where changing them isn’t going to improve them. It might even make them worse. […] The iPhone? It’s boring. And it’s probably going to remain that way for the foreseeable future. It’s not bad, it’s just the march of time and technology. Revolution becomes evolution. — Mat Honan
