Hi Tim,
Great question. I actually had to write a justification around this to help convince the publisher my book would make a different contribution. First, Krug's book is considered a staple read for anyone working in design. So I know he's done a lot of things right. My book is not meant to be a replacement of his, rather a compliment. That said, let's talk some major differences:
Krug covers concepts that are similar to many I discuss, without going into the deeper understanding of why. My book will also teach you why, from a psychology/research focus, certain design elements are effective and when. I think much of what is covered by Krug can be found in chapter 3 of my book which discusses in-depth heuristics or mental shortcuts people use.
Design for the Mind discusses the building blocks of behavior. For example, chapter two will show readers what leads to behavior (e.g. use of your product) and how you can move people from non-users to users. Don't make me think looks at it from the perspective of someone has landed on your site, what is the next thing they will do? I will show you how to even get people to your site/product to make that decision. I spend chapter two discussing a principle meant to develop your potential and current users into long-term loyal users.
Design for the Mind focuses heavily on how to effectively communicate. I dedicated chapter 7 to discussing framing communication. Communication being much more than words, but visual communication as well. I provide insight into how to effectively convey your message to users, in a way that will motivate their behavior.
I've also included a number of activities for readers to engage in if they want to practice the skills they are learning. Chapter 9 is a comprehensive case study/review of how all the principles can work together. Krug's book doesn't contain these elements.
Both Krug and I have one common mantra - something along the lines of "Know your User." We both advocate research with real users and taking action on the insight user research can provide.
Overall, I think there are large differences between the two books. I hope this helps provide some insight.
