This! That was, IMO, a golden era for UI design. We've lost SOO much to the wild west experimentation brought on by the advent of touch interfaces. A really strong shared design language across apps and vendors is an unbelievably valuable productivity enhancer that lets people apply the intuition they've learned in one app to a UI in a different app that they've never seen before. When everyone tries to make their app look and feel and operate with uniqueness and visual distinction, much is lost.
