Enlightenment
When I was a boy, I read fantastic science fiction stories, in which the heroes possessed amazing devices. Some of these devices would allow the heroes access to the full range of human knowledge, at little more than a thought. Some would grant the heroes instant communication with anyone or everyone. Some would offer the heroes entertainments, with all of the books, music, or movies every created available whenever the heroes wanted.
Now that I actually carry around anywhere between three and six of these devices on a regular basis, I mostly spend my time annoyed at battery lifetime.
