Penny for your number

Recently phone books were delivered in my neighborhood, which brought several thoughts to mind:

1. Does anyone use phone books anymore?  With nearly everyone possessing a smart phone, tablet, or laptop computer, it is literally easier and faster to look up a phone number using 1 of those devices than to pull out an archaic phone book.  It would be better to have a couple phone books at the library for those who don't have a smart phone or computer.
2. Does anyone have a landline anymore?  Most of the people I know have gotten rid of their landline phones since they are more easily reached on their cell/mobile phone.  Although many of us work in offices that have landlines, I just look up a needed phone number on the internet.  And since cell/mobile numbers are not printed in phone books, it makes the phone book seem even more obsolete.
3. Isn't it a huge waste of money, paper, and labor to blanketly deliver phone books unsolicited?  I can understand printing a small amount of phone books for libraries and people who actually want them, but why not simply make these available for use or pick-up at a library or phone company office?  Indiscriminately delivering multiple phone books to every house costs money to print and money to deliver the books, which in my case, went directly into the recycling bin.

To ad insult to injury, we received 4 telephone books.  You see, our house is on a corner and we have a driveway next to our front door and a driveway next to our side door.  The geniuses hired to deliver the phone books didn't realize it is just 1 house, so they dropped off 2 books at both of our driveways.

It is my belief that the phone book is just about as obsolete as the penny; for some reason they're still in circulation although neither are necessary.
