I disagree that skeuomorphism is only about taste. It's not just a skin, it also removes and limits functionality. I can even give specific examples. If you have lion, go to your address book. It probably opens and lists people on the left with their details on the right. It looks like a book. Can you group people? It's certainly not obvious that such functionality (which is useful!) exists. Now click the red bookmar…
Skeumorphism is purely about looks. If it impacts functionality it’s more than that. If it’s only looks it doesn’t matter and is only about taste.
Further, looks are about much more than just taste. Designs affect how easy it is to understand the information being displayed, or to understand how to use an application. Skeuomorphic design is typically used to try to improve the latter: help people to understand how to use the app. It mimics a physical object because people already know how that object works. This benefit disappears if your skeuomorphic design doesn't actually work like the object it mimics though.
