Can we just make this the auto-reply comment whenever someone mentions skeuomorphism on the internet? I couldn't be more sick of the concept, except when I hear it constantly being used incorrectly. Textures and styles aren't skeuomorphism, skeuomorphism is imitating real-world objects to provide a sense of familiarity in execution. Not a notes app that looks like a notepad, a notes app that FUNCTIONS like a notepad.
You're overly restricting the definition of skeuomorphism, or perhaps confusing it entirely with anachronism. Wikipedia's definition of skeuomorphism is a design element that is retained as an ornamental imitation of a formerly functional counterpart. When a notepad app wastes screen space on drawing non-functional spiral binding, that's definitely skeuomorphism.
However, that doesn't mean every thing -- like the leather stitching in "find my friends" -- that Apple does involving natural textures is skeumorphic.
