Death of conversation?
I personally do not have a problem with portable media because our devices facilitate our lives. In fact, my friend and I have developed: Dose Of News: All the news that's fit to download. Read all about it. http://www.doseofnews.com
But I strongly believe digital media is making people engage less and some may forget how to interact face to face. This worries me to some degree because I see too many people everywhere I go, from NYC to Shanghai seemingly obsessed with their smartphones and tablets.
