Thanks are due to the many people who answered questions I raised on Twitter, Facebook, and my blog in the course of writing Smartphones and beyond. Thanks are especially due to the various people who encouraged me to take the time to write this book, and who provided helpful comments on reading drafts of various chapters.

Smartphones and beyond no doubt still contains a host of factual mistakes, errors in judgement, misattributions, personal biases, blind spots, and other shortcomings. All these faults are the responsibility of the author. To suggest changes, either in an updated edition of this book or in some other follow-up project, please get in touch, via the links in the website

Where the book includes copies of excerpts from Internet postings, I have indicated the online location where the original article could be found at the time of writing. In case an article has moved or been deleted since then, it can probably be found again via search engines or the Internet archive, If I have inadvertently failed to give due credit to an original writer, or if I have included more text than the owner of the original material wishes, I will make amends in a later edition, upon reasonable request. Quoted information where no source is explicitly indicated is generally taken from copies of my emails, memos in my electronic diary, or other personal archives.

One of the chapters of this book is entitled “Too much openness”. Some readers may feel I have, indeed, been too open with some of the material I have shared. However, this material is generally at least 3-5 years old. Commercial lines of business no longer depend on it remaining secret. So I have applied a historian’s licence. We can all become collectively wiser by discussing it now.

The various NDAs (non-disclosure agreements) which were signed over the years, to ensure commercial confidentiality during the heat of smartphone creation projects, have expired with the subsequent passage of time. The bigger picture now is that other emerging technology sectors risk repeating the stumbles of the smartphone industry. Whereas the smartphone industry recovered from its early stumbles, these other industries might not be so fortunate. They may die before they get off the ground. Their potential benefits might remain forever out of grasp, or be sorely delayed.

If the unflattering episodes covered in Smartphones and beyond can help increase the chance of these new technology sectors addressing real human need quickly, safely, and fully, then I believe it will be worth all the embarrassment and discomfort these episodes may cause to Symbian personnel – me included. We should be prepared to learn from one of the mantras of Silicon Valley: “embrace failure”. Reflecting on failure can provide the launchpad for greater future success, whether in smartphones, or beyond.
