Apple announced the new iOS to be available in the Fall.
You can read about the various features and compatible iOS devices on the iOS 8 page.
Each of the above features are designed to allow you to search better, type more efficiently and do more from within other apps.
Apple says the new keyboard is smarter and “8 makes typing easier by suggesting contextually appropriate words to complete your sentences. It even recognizes to whom you’re typing and whether you’re in Mail or Messages. Because your tone in an email may be different from your tone in a message.”
Family Sharing brings the promise of allowing you to share App Store purchases, iTunes and iBooks among your family. When one buys something, all can share.
iCloud Drive will allow you to save to iCloud documents and folders you want to access from any iOS device, Mac or PC.
