A second grader's cellphone - the Migo.

[interviewer asks second grader]: "Are you afraid that someone might steal [your phone]?" [second grader responds]: "That would be silly, too. They can only call my parents. One time a boy at school wanted to press the 'EMERGENCY' button, but I wouldn't let him. That would be irresponsible. I am not allowed to do that." (this article made me smile...)
