I could really live without modern technology (or twitter, facebook etc.) as long as no one else had it either, lol
I really think that it is a "Keeping up with the Jones" thing. Who wants to be left out when all your friends are doing it, right?
Just think about the frontier age or the dark ages. What did they do to pass the time? Probably whatever their friends or family was doing.
Funny how the world evolves and we all follow suit, or be left out in the cold, IMO
