Query: Hmmm...I am not sure

This book started out on a great premise, to talk about smart technology, smart materials and smart design in residential house. Examples illustrated in this book are not bad, either. Layouts are there, pictures are there. Descriptions are quite well-written. Still, this book is lacking of that wow factor that manages to captivate our interest, or perhaps, to keep us reading from beginning till end. Perhaps, it is the quality or the presentation of this book. It is printed in Hong Kong and compared with books done by Taschen and Phaidon, this book is definitely of a more inferior quality. My conclusion is simply, hmmm...I'm not sure. Keep up the good work, though.
