"Once upon a time, voice mail was useful," said Yen Cheong, 32, a book publicist in New York who has transitioned almost entirely to e-mail and text messaging. According to her calculation, it takes 7 to 10 steps to check a voice mail message versus zero to 3 for an e-mail.
"If you left a message, I have to dial in, dial in my code," Ms. Cheong said. "Then I mess up and redial. Then once I hear the message, I need the phone number. I try to write it down, and then I have to rewind the message to hear it again," she added, feigning exhaustion.
