"In recognition of the widespread use of iPad sin schools and general education, Apple recently released a new "Apps for Teachers" http://bit.ly/16HvwHx category in the App Store. You'll find them listed among a wide and extensive list of categories under the "Education Collection" banner."
Been thinking this for schools ever since the feature came out. iOS 7 hadn't been out for a week when I saw the first story of a school losing the ability to use an iPad because a student left in a hurry and they did not have the password to the Apple ID. There needs to be a way for the owner of the device to over-ride the deactivation.
Under iOS 7, we've got a neat new ability to access links from Twitter right within Safari. And if you've got multiple accounts, it'll pull in the links from all of them, organized into one handy little tab.
