Shared iCloud Photo Streams
Anyone invited to a Photo Stream can now add new photos to photo streams, supports video sharing as well
Siri
Siri gets a new interface, can switch between male and female voices without the old trick of changing languages, can perform system tasks like “increase brightness”, integrated with Twitter, Wikipedia, and Bing Search is now integrated
iOS in the Car
The iOS interface can now be outputted to in-car displays with support for Siri, Maps, iMessages, Phone, and more. Will debut in 2014 with many, many car manufactures.
App Store
The App Store gets a huge refresh, and apps automatically update in the background now. New ways to find apps based on age recommendations or location.
iTunes Radio in Music App
iTunes Radio is a streaming music service from Apple, built into the Music app. Featured Stations, create your own stations, share stations with friends, buy songs directly from iTunes Radio, skip songs
FaceTime Audio Calls over Wi-Fi
You can now make audio-only FaceTime calls without the quirky tricks of enabling audio-only
Phone, FaceTime, and Message Blocking
No more funky block lists to block annoying callers. You can now natively block anyone system-wide from calling you, facetiming, or sending messages and texts
Notification Syncing Between Devices
Acknowledge a notification on one device, and you don’t have to see it on your other devices. Syncs with OS X Mavericks and allows for cross-platform notification management and alerts.
Activation Lock
A huge anti-theft deterrent, Activation Lock ties iOS devices to Apple ID’s and allows you to block a device from being used, even if it was formatted or restored. Prevents stolen iPhones from being used by anyone except their rightful owner.
