Android 4.2. will be able to differentiate users

According to the Android Police resource, one of the key changes to Android 4.2. will be support for “multi-profile”.

The essence of this feature is the possibility of having multiple accounts on one device. Thanks to this, Android gadgets will be able to become, in the full sense of the word, family, since each user will have their own settings and their own contact databases.  

Moreover, if it is necessary to control the purchases of other users, the main one (apparently, some kind of “administrator” in the usual Windows) will be able to use PIN-code blocking and age rating accounting.  

The Google Play app Store will also receive multi-profile support after the next OS update. Apps purchased by one account or another will be automatically remembered. And Google Play itself will give recommendations on applications to each user separately.
