The whole "Apple's skeuomorphism is bad" meme was blown out of proportion. Hundreds of millions of people use bloody DVD/Video/Music player UIs that resemble in tiny detail AND behavior an actual dvd/cd player for no good reason, and then complain about the "leather stitching" on iCal, which is a purely _cosmetic_ addition.

The BAD kind of skeuomorphism is mimicking real life object behavior, when a different approach is both possible and more easy to use in software. That is, UIs like this:

It has nothing to do about having faux-leather on your background.

Page flipping, which Apple uses in iBooks, is such an example of bad sceuomorphism.

But most other Apple's sceuomorphism criticism is about irrelevant fad designer preferences for clear-cut modernist LOOKS (e.g Metro style, flat etc). Those things are fads, and come and go. The same guys were all over "lickable interfaces, drop shadows, embossed elements, etc" a few years back. Actually, circa 2005-7, it was a whole movement of developers using such visual sceuomorphic and ornamental details, named the "Delicious Generation".

To see that the LOOK part of design (and not behavior, e.g look&feel) is all about fads, consider the case of Jonathan Ives again. The same "minimal, aluminum+glass" guy, was the one who designed the flower-power iMac back in the day:
