Status Anxiety
I found this documentary from 2004 called Status Anxiety by Alain de Botton on a CD while sorting the crud on my desk. I found it fascinating and and thought provoking at the same time. Also sad in a way. I can't help but think of the iPhone when I watch this.
There might be better quality versions flying around your office or pick it up on DVD for cheap. This is just part of the 2hr doco.
You can also buy the book on Amazon but why read when it can be spoken to you by the author himself.
