Acknowledgements
Some people told me it would be hard to write this book in and around my real job in the System Management Group at Symbian and a few promised me that it would be impossible. They were all right, of course, although none of them tried to stop me.
Many thanks to Wiley and Symbian Press therefore for their patience as I've stretched deadlines. Thanks to Fredrik Josephson for saying 'yes' to my starting the book as a 10% task and for turning a blind eye when it grew beyond that; and to Geert Bollen for being (almost) tolerant when he inherited the problem. Thanks to Freddie Gjertsen of Symbian Press for getting me to the end and to Phil Northam for his part in making it happen in the first place.
My biggest thanks, though, are due to those who took the time to talk to me, agreed to my using a recording device and let me use their words. They are: Geert Bollen, Martin Budden, Andy Cloke, Charles Davies, Bob Dewolf, Morgan Henry, lan Hutton, Peter Jackson, Keith de Mendonca, Will Palmer, Howard Price, Murray Read, Martin Tasker, AndrewThoelke and David Wood. I have done my best to make sure they are happy with the use to which I have put their words.
I am also very grateful to my technical reviewers from across the company (and, in a few cases, from outside it): Jan van Bergen, Chris Davies, Warren Day, Roy Hayun, Simon Higginson, Mark Jacobs, Martin de Jode, Andrew Langstaff, David Mery, Matthew O'Donnell, Kal Patel, Dominic Pinkman, Matt Reynolds, Alan Robinson, Mark Shackman, Phil Spencer, and Jo Stichbury. Jeff Lewis provided a final review from a commercial perspective.
Any errors which remain are mine, of course.
A special thanks to Jawad Arshad for his help in constructing the reference material in Appendix A, and for his careful review of what
I did with it, and to Bob Rosenberg for his great work on the System Model graphics (which is present in the book in the form of the color pull-out). Way back when, Martin Hardman was my original collaborator on early versions of the System Model, and I would like to acknowledge his contribution
Finally, my family have put up with this book for longer than was promised. Philippa, Nat, Jake and Henrietta - thanks.
