I was eager to wait for this book initially, thought the book would given same information as what I had read on Nokia. The book is I-Mode strategy and I think not much strategy were discussed by the author.
I think Natsuno-san, is not "open" enough to discuss about I-Mode strategy.
The writings are basic about I-Mode and what the progress. This is not a worth purchase. I think the readers would more interested about how they build I-Mode at the beginning (not technical way) like the branding strategy, policy and etc. There is a lot of issue had not been discuss in the book.
