This is a great interview. I use this as the "reading" for the first day of class in my course "Behavior and the Designed Environment" because Don introduces many of the fundamental questions or concepts we will be addressing.

UX Week and MX were two of the greatest conferences I've attended in recent memory. The speakers were brilliant and the discussions in between sessions were remarkable.
If you've got a chance to attend either UX Week or MX you won't be disappointed.
You can hear Don and Peter talk further over on Boxes and Arrows from this event, if of value. boxesandarrows.com/view/user-experience-week Cheers!
