Keyboard: A new keyboard in iOS 8 will use predictive typing to speed up input. As you type out words with the new keyboard, recommendations for the next word based on common phrases will pop up; you can then add those to your message. We've seen this a bit with the keyboard in the SwiftKey Note app, but Apple's solution goes a bit further to learn your personal voice (all the while maintaining your privacy, Apple executives were quick to add during Monday's keynote.)
Continuity features: Apple wants better integration between all those devices you own, so iOS 8 is going to let you pick up on your iPad what you were doing on your iPhone. That includes taking phone calls on your tablet by more easily creating a portable hotspot for sharing your phone's connection.
Messaging: Enhancements in the Messages app in iOS 8 focus on group messaging; you can add and remove people within a thread. Other enhancements let you name your thread for easily tracking or turning on a Do Not Disturb setting for a particular thread. You can share your location with people in a conversation;if they've shared with you, you can see their location on a map.

A useful addition to Messages is a Tap to Talk feature that sends audio or video messages to contacts--and yes, it works with selfies, too. Best of all, you can listen to and interact with these to messages right from your lock screen just by putting your phone up to your ear.
iCloud Drive: iCloud Drive promises a better way to work across applications in iOS 8. For example, if you're working in an app such as Sketchbook, you can open up a document from another application and edit them in that app.
HealthKit: Craig Federighi, Apple's senior vice president of software engineering, lamented how different health wearables are unable to talk to each other and share the information they gather. iOS 8 looks to address that problem with HealthKit, an attempt to take health stats and put it in a central repository so you can manage it all from one app. Partnerships with the Mayo Clinic and Epic Systems (who provide software for many major hospitals and healthcare organizations) will make it easier for iPhone users to share key health statistics with their doctors, in order to better manage their health between checkups.
Family Sharing: iOS 8 introduces better management features to let family members easily share photos, location, reminders, and many other pieces of information with each other. The chief benefit here: You're finally going to get to share music, movies, and TV shows you've bought with other family members. You can hook in up to six devices. Parents in particular will appreciate new notifications that alert you when your kids try to make a purchase.
