So it is a touch shocking that Apple, of all companies, has something of an internal riot on its hands.

Why?

The problem is something called skeuomorphism, which is when a software user-interface is designed in a way that mimics design from the offline, non-software world.

For example, the place where readers go to open up iBooks on their iPads looks like a bookshelf (see above).

Apple loves skeuomorphism because Steve Jobs loved it, and current software boss Scott Forstall does too.

But Austin Carr has a long story in Fast Company about how some of the designers who work for the company—including rock-star designer Jony Ive—are sick of it, and that a "revolt" is close to breaking out.
