From Don DeLillo's short story "Baader-Meinhof," published in The New Yorker in 2002:
His cell phone rang. He dug it out of his body and spoke briefly, then sat with the thing in his hand, looking thoughtful.
"I should remember to turn it off. But I think, If I turn it off, what will I miss? Something so incredible."
"The call that changes everything."
"Something so incredible. The total life-altering call. That's why I respect my cell phone."
