Key security feature announced is multiple user profiles
QUOTE: Google announced also Android 4.2 on Monday. It’s still called Jelly Bean, just like the prior version, but it’s made just a little bit sweeter by the addition of new features such as Photo Sphere, Gesture Typing, multi-user support and more. Sharing an Android tablet with a family member will be significantly less awkward thanks to multi-user support. Each user can have his or her own homescreen, background, widgets, apps and games. Toggling between users is supposedly as easy as switching between apps.
