Apple has just released the first beta of iOS 9.3 to its public beta testers and developers. The company regularly releases beta versions of its operating systems, but this update is unique because Apple has put together several pages extensively detailing its new features, something we normally don't get until we see the release notes posted with the final version of the update. Collectively, this list of new features will make 9.3 the biggest release since iOS 9.0.
The first and most significant is a multi-user mode for iPads, aimed primarily at schools where buying a single iPad for each student is too expensive or otherwise undesirable. From Apple's description, it sounds as though each student will have a roaming user profile that follows them from iPad to iPad so they can access the same apps and data no matter which iPad they use to log in. User content can be cached so that students who regularly use the same iPad won't have to wait for data to download each time they log in.
These new user profiles are just one part of a larger group of features meant to make the iPad more appealing for schools. The "classroom" app gives teachers a bird's-eye view of their students and what apps they're using. The app can be used for screen sharing to help students out when they need it or to lock students out of specific apps when they're not supposed to be using them. The Apple School Manager can be used by administrators to create Apple IDs, purchase apps, and manage devices. And a new type of Apple ID, the "Managed Apple ID," can be created and assigned by schools independently of students' normal Apple IDs.
All of these new education features are aimed squarely at Google's Chromebooks, which despite (or because of) their limitations have seen a lot of adoption in schools. Many of the things that iOS 9.3 will add to the iPad (easy account and device management, roaming profiles and content, and so on) are features that Google pushes hard in schools. As Chromebooks have risen in the educational market, the iPad has suffered several high-profile setbacks—it makes sense for Apple to follow Google's example here.
