One of the features that most check missing in Android tablet is the support for multiple user accounts. The tablets are not a personal device, you use several members of a family, and to maintain the privacy and not have that be deleted accounts whenever we take the tablet need to support user accounts, something that looks like that It will come in the next version of Android.
It has discovered references to the management of multiple user accounts in the source code for Android 4.1 (Jelly Bean), code to create a user, delete it, change account and folders each application data kept for each user.
You are expected to support multiple user accounts for tablets comes at the end of this year for the next version of Android 4.2 or 5.0. Mobile user accounts have no much sense since they tend to be personal devices that only the usa a person.
