Now that OS X El Capitan and iOS 9 are available to everyone, Apple's updating its iWork productivity suite to take advantage of certain new features. The refreshed Keynote, Numbers and Pages apps come with support for 3D Touch and Force Touch, as well as Slide Over, Split View and Picture-in-Picture modes. But keep in mind some of these will only work if you have compatible hardware, including the iPhone 6s or 6s Plus and the ultra-thin MacBook -- either way, you'll need to have the latest versions of iOS and OS X installed. In addition to this, you can also preview shared Keynote, Numbers and Pages documents on iOS and Android browsers, while iWork '08 and '06 users get the ability to start opening and editing files. Lastly, Apple says iWork for iCloud is officially out of beta and there are "many new features" on the service, such as support for 10 extra languages and a way to comment on docs.
