Responsive Design for Drupal

It was interesting to read Responsive Design for Drupal after doing several webapp projects with Bootstrap.  This book is ideal for anyone with basic Drupal theming skills looking to add responsive design to his/her toolbox.   For someone such as myself with responsive design webapp skills but few drupal skills, it doesn't get me there all on its own.   I like that it is short enough to get you going fast, and technical enough to get you good breadth.
