I think that simplicity still applies, even in interfaces which aren't considered simple. It's just a matter of how you conceive simplicity. John Maeda talks about "thoughful reduction". It's not less for the sake of less; you take away while it makes sense to take away. That's simplicity. Clutter isn't the opposite of simplicity. Simplicity has to be conceived always factoring in the scope of the design. If something is necessary and you remove it, you're not making your design simpler, just dumber, limited or crippled. tl;dr: simplicity will look different in different apps. Photoshop will always look more cluttered than the prospective and portfolio-enriching weather app which is featured on Dribbble.
