Yes, I like how they're striking a balance between minimalism and skeumorphism. They often try to do more with less. The Photo Booth one is a good example. Away with that camera: Let's focus on the strip from a photo booth (and don't use actual photos because that's too messy at smaller sizes).

It looks like sometimes this approach has led to more details or an entirely different design, and sometimes less details. Almost like a normalization of sorts to better standardize around a level of details and amount of contrast and brightness.
