Interesting - one of the presentations I found was this one on Design Insights From Apple's iPod (2006).

They highlight:

- core design team

- start with an idea for an unmet customer need

- drive innovation from imagining user’s experience

- define essentials for “insanely great”

- simplify to great lengths to hide complexity

- grow user involvement through evolution
