Rene Ritchie, writing for iMore:
Almost everything we saw last week was built upon what came before. The physics-based redesign of 2013 set the stage for the slamming, growing, shrinking, and secret-hiding new message effects. The extensibility and continuity of 2014 allowed for everything from secure app transactions inside Siri and Maps to using one device to authenticate another. The intelligence and convenience of 2015 has now been multiplied and accelerated across platforms. And the confluence of all these technologies, planned and serendipitous, has allowed Apple to create software and services that offer power matched only by its unprecedented respect for personal privacy.
Astute analysis, as always, from Rene. This is a big year for Apple and accessibility.
