I got this book as a gift from my uncle, who was teaching an innovation course for MBA students. I read it in 3 days, and fell in love for the subjects of innovation and interaction design. Well, 4 years have passed, and today I've finnished my MBA, have started an Interaction Design post-grad and I'm working with New Product Development at a big computer manufacturer, trying to spread Design Thinking throughtout my company. This book was the first to really change my life for the better... Thanks IDEO...!
