Of note to me are the changes to Notification Center (especially the calendar stuff), and how many little things are getting synced up behind the scenes via iCloud.
This is Apple’s game. Small changes that have a huge impact on usability, which aggregate over time. These don’t look like a lot on paper. But if iCloud is still around in 3 years, we’ll be able to look back from there on its original incarnation and they’ll be lightyears apart.
