The idea behind my Crystal Interface concept came from trying to find a balance between current skeuomorphism heavy iOS apps and the more digital metro UI on Windows phone. The challenge was finding a way for the platform to evolve without making drastic changes because it needed to remain familiar to the huge iOS user base.
I believe a balance between the two directions may be possible. Like Apple focusing on the content and letting hardware fade away into the background, the same needs to happen for the UI.
