One of the education features allows students to log into any shared iPad and make it their own. I hope this is a precursor to full multiuser support in iOS 10. All they have to do is implement it with Touch ID and otherwise similar to OS X and it will be amazing. That would be so perfect for a family iPad for kids.
This doesn't necessarily translate to personal use. Can pretty much guarantee you this operates like everything else in the education space. The iPads are blank slates with just the necessary apps the students would be using. Student user/profile data is stored on local servers so when the student logs in their data is downloaded and when they log off everything is deleted. This works great for education but no so much for personal.
The reason Apple doesn't implement this for personal use is storage requirements, it would just be a terrible experience on the lower capacity devices.
