This is SO true on both sides of the coin. Yes, I cannot live without my smart phone and I just might yell at it if it doesn't work. It is like my 4th child! I depend on it to love me back, just like my children. :)
Yes, I've been known to talk to people with my phone in hand doing other things as part of the conversation .. actually quiet often! I don't have a little wallet of photos in my purse anymore, I whip out my cell phone and share photos and videos!
Yes, I've found friends for Facebook right away in the middle of a conversation.
My smart phone really has changed my life in more ways than I can imagine.
Have fun and a laugh on me -- go watch the above video!
