If you are interested in the philosophy of technology, skip this book and keep looking. Borgmann defines technology as developments since the industrial revolution. Many of his claims may stand within this narrow definition of technology but lose their force when considering technology in a broader sense.
Rather than a critique of technology, the book actually critiques consumerism. In this, the book is thought-provoking and worth reading. Although Borgmann assumes (incorrectly, I believe) a linkage between technology and consumerism, the linkage is not necessary to the critique of consumerism. Unfortunately, like most social critics, Borgmann does not present tangible suggestions for changing course.
