If anyone has the WWDC app watch the What's New in iOS 7 Interface Design video. Speakers are Greg Christie and Mike Stern. They do a great job of explaining the thought process behind the redesign. It really gives you a sense of Apple's vision for the future. One thing I took away from it was the use of gestures, animations, translucency, etc. to provide a life like feel and sense of enjoyment rather than going into great detail to create a visual representation of a physical object. The notes app was used as an example. The previous app design (from 2007) was designed to look like a physical notepad because using touch screen devices, swiping, pinch & zoom, gestures, etc. were new to people. So recreating the physical was more necessary for people to feel comfortable. But now that people are so familiar with using these devices it's no longer necessary. And certain things that don't make sense (like having a search box when there's no search functionality on a physical note pad) is gone. That was just one example. It was a really interesting (and non technical) video that shows a lot of thought did go into this re-design. While iOS 7 UI still needs work and a lot of polish the thought process behind it seems very well thought out and make sense. I'll be really interested to see what 3rd party app developers do with their apps.
