I don't know if you endorse the message behind that photo or not, but I've never taken someone out to dinner who busted out the newspaper while I was trying to talk to them.
There is a difference of enjoying each other's company while being quiet and being rude while ignoring someone else. I wish some very talkative person wanting me to entertain them on the bus could have been entertained by their phone. I've often used books/ereaders/phone to keep others from talking to me (and enjoying reading of course). I think one major thing to discuss is not how much we're being distracted by technology, but more of how much priority we put on socializing face to face.
