Great, long rant by Tog on design: "Today, people are forced to remember arbitrary gestures and placements. We never know whether something is permitted or not. When we accidentally touch the screen and the system takes us somewhere new, there is no way to back up and get to the earlier location—we most often have to start all over again. The designs appear to have discarded the science and Apple’s own experience in interaction design, an area in which Apple was once the leader."

Another excerpt: "Good design should be attractive, pleasurable, and wonderful to use. But the wonderfulness of use requires that the device be understandable and forgiving. It must follow the basic psychological principles that give rise to a feeling of understanding, of control, of pleasure. These include discoverability, feedback, proper mapping, appropriate use of constraints, and, of course, the power to undo one’s operations .... Good design emphasizes the usefulness of a product while disregarding anything that could possibly detract from it .... These are all principles we teach elementary students of interaction design."
