As someone who spends 50% or more of his professional life teaching, training and tutoring persons from the ages of 6 to 96 on a variety of Operating Systems and hardware, I can't even begin to tell you how welcome a return to skeuomorphism would be. It doesn't have to be the *same* designs as before, but a UI that functions like real-world objects will be a huge, huge boon. Clarity (make things you need to click/tap look like actual buttons again), visibility (reduce the use of low-contrast UI design elements and bring color back to elements that have been reduced to grey and grey), and consistency need to return as well. Our wonderful, consistent Apple-centric micro-world, where software all looked and functioned in at least a reasonably similar fashion in the Apple world has spent the past 15 years tumbling into an abyss of random ******tified crap that feels an awful lot like Microsoft at their worst. This design may include skeuomorphism, and maybe consistency, but it still appears to desperately lack clarity and visibility.
