Those books are good but I am a fan of some of his writing for the New Yorker. Here is a selection (with links):
- Smaller: The Disposable Diaper and the Meaning of Progress -- a salute to one of the greatest inventions ever.
- The Bakeoff: Project Delta aims to create the perfect cookie -- describes a product design process involving several competing models.
- The Moral Hazard Myth: The bad idea behind our failed health-care system -- a nice descriptions of the problems associated with health insurance. See my comment on similar issues in Australia.
- The Televisionary: Big business and the myth of the lone inventor -- the story of Philo Farnsworth and the invention of television.
There are many others but this is a good start.
