We’ve already found the code in Jelly Bean for multi user support. It’s nothing new, even if it isn’t working very well. At least we know Google is working on it! They just acquired a patent that uses Face Unlock to differentiate between multiple users. This is of course the next step, and hopefully this system will be done by the next Android version next year.
Nice feature to share apps via multiple devices...I usually hand down my devices to my wife or daughter so it'll be nice to not have to pay for the same apps multiple times depending on who is logged in.
Oooh hand my kid a phone and based on their face it could lock out certain apps, connectivity, or other features. I can see how this could be useful.
