Do you have an example where the skeuomorph may work better than a re-imagined design?
I think Luxylight (luxylightapp.com) is a good example. It looks kinda like a car key fob. Are there better ways to do a flashlight app? Maybe. But this interface is intuitive and I knew exactly what to do when I opened it for the first time. That experience and design doesn't get in the way of the function here (turning my iPhone's flash on), therefore it is good design.
I believe that there isn't a black/white argument about whether it's better to use skeumorphic principles or interface-specific constraints in most situations. I think both can co-exist. Frankly, I think you can have a flashlight app that is skeumorphic and an app that is simple and flat, and both can function just as well as the other.
