The book is an interesting concept, however, it's title doesn't directly correspond to its content. The text presents itself as a rant, criticizing every bad design the author has come across in his lifetime. Moreover, it is made to seem that the book's main argument is that anytime a person has difficulty with a device/object/etc, it's the fault of the designer. This narrow view transforms into a psychological text about how humans perceive objects and how memory works.
If you're looking for a book on 'design' as in creative design and the design process, then this isn't the book for you. The book is dated and doesn't correspond well with our present time.
