As a followup on this, it's notable that Apple has changed the title of the linked post to "Apple introduces a delightful and elegant new software design", making the subtitle "A universal design across platforms brings more focus to content and a new level of vitality while maintaining the familiarity of Apple’s software"

Everyone was keying on the universal design thing, and the seeming importance of "introduces" as if this is a first, and it was such an odd thing for Apple to denote given that they have been using a universal design for a long, long time.
