Pocket-Lint: Apple's CEO Tim Cook has given his first on-stage performance outside of the usual Apple keynote product launches at the Wall Street Journal's All Things Digital conference in California.

The "fireside chat" saw the cool and collected chief executive talking on a wide range of topics, from working with Steve Jobs to his thoughts on Facebook and Apple's Siri for the iPhone 4S. (Apple TV, Culture, Facebook, iPhone, Tim Cook)
