I cannot believe that someone gives a book 1-star rating just because (s)he didn't find the ToC of a book. This is not fair to a decent book. I read this book while completing a research paper on comparison of mobile computing platforms. The chapter that introduces the architecture of Symbian OS and Symbian C++ development framework is very clear and comprehensive. Given the many components of Symbian platform, I would say it's worth reading.I rate the book as a 5-star one to counteract the first comment. Seriously this is a 4-star book.Btw: Amazon normally does not put the ToC of a book online. You can search for ToC on the publisher's website.
