Scott Stevenson provides a very interesting essay, Satisfying UI Design is Often Illogical, discussing the impact and need for UI changes and the expectations of and reactions by the market to those changes. The entire piece is well worth a read by anyone interested in design and user experience, with many valuable insights. One of my favorites though is encapsulated in a single line: “The real goal is user satisfaction, and some of that is really illogical and messy.”
