Taking a seat at the All Things Digital conference, Tim Cook touched on a number of topics without revealing anything too delicious – including questions about an Apple TV, his role at the company now during the post-Jobs era, and Facebook, among some other things – but he also revealed a little tidbit about the beloved iPhone 4S. It’s true; as some may have guessed, the ‘S’ in 4S definitely stands for Siri. On top of confirming this, he also did take the time to acknowledge that, in its current state at least, Siri does still have its bugs. When it works, it’s an excellent product, but it often doesn’t.
