A new novel that I believe is well worth a look is Daniel H. Wilson's "Robopocalypse":

The book chronicles (in a non-Terminator way!) an idea about machines becoming self aware and what that would mean. If you liked Max Brooks' "World War Z" chances are you will like this book as it's told in a person narrative form as well.
An excerpt? A creepy part is when a little girl's doll (Buttercup) that has adaptive intelligence becomes "alive" and begins to talk to her, and calls her by her name:
Quote:
"How come you know my name? You aren't supposed to know my name, Buttercup."
"I know lots of things Mathilda. I have gazed through space telescopes into the heart of the galaxy. I have seen a dawn of four hundred billion suns. It all means nothing without life. You and I are special, Mathilda. We are alive."
