Digitally re-creating real materials and analog objects very quickly becomes aesthetics for aesthetics sake. It’s hard to believe that all but a minute percentage of Apple’s user base has a tan-suede–bound calendar or book of any sort, or anything else that looks remotely similar. Unfortunately, these are the characteristics of skeuomorphism that a vast majority of UI designers employ when they use this approach… Ultimately, it encourages designers to become less critical and less inventive, which is detrimental to evolving new and improved solutions.
As a designer it’s like I have 2 little guys on my shoulder at all times. One that says “COMON MAKE IT SHINY AND BEVELED AND GLOSSY AND LICKABLE LIKE APPLE AND COOL AND AWESOME”, and another that says “No.”
