Thank you for this review. Much appreciated!
The book gets updated twice a year in order to keep it as up-to-date as possible. As Rat says, however, keeping up-to-the-nanosecond is pretty tough in a market as volatile as this one is!
I've taken Rat's constructive comments on board and they will make it through to the next edition of the book which will be coming out later on this year. An iPad version of the book is also on the cards, which will include an optimised layout specifically for ebook readers including bigger and better photographs and a different layout for tables.
Thanks again, Rat!
