I enjoyed the main point of this book, which, as the title makes clear, is about the need for humans to slow down and enjoy life.
The problem I had with the book is that throughout, the whole thing feels dated. Not only in his specific examples of technology (this was published before the iphone, for example), but in his general conviction that this is a "worldwide movement," which it may be, but I've never seen it outside this particular book.
Each chapter is devoted to one facet of human existence that we could slow down: food, sex, child-raising, etc. And in each of these, I agree that there are probably some people out there who are interested in making these things slower. But the only part of the book that I think actually constitutes a "movement" is the Slow Food movement, which has managed to penetrate into general cultural consciousness.
Anyway, I found that dated nature of the book distracting, and it really felt as though I were reading something that was a product of its time, even though that time was less than 10 years ago (!). It really felt as though it was written in the 1990s.
