Query: Basic theory in Human Interface Design. Nothing new.

If you're a beginner in the world of Human Interface Design, this book is for you. If you're a programmer looking to make his/her program more user-friendly, this book is for you. Otherwise, for anyone else, the theory and concepts are basic at best. I'd recommend tracking down the long out of print Apple Computer "Inside Macintosh" series of books as they are more detailed and written by some of the pioneers of Human Interface Design.The one redeeming point here is the quality of the screenshots. Very impressive indeed and help to get the point across. Otherwise, you may find this book an entertaining read, but not something you'd learn a great deal from.
