Who Needs This Book?

[byoung]

I have the 2nd edition of this book published in 2007 (ISBN 978-0-273-70806-3). The author has removed most of the calculator references. After discussing the history of the spreadsheets he has used (VisiCalc, Lotus 1-2-3), the only mention of calculators is the following:

"The author once needed to analyse lease profitability and wrote models in Basic or using HP41 calculators to review different portfolio funding strategies. After great time and effort, the models worked and provided an answer, but they were unclear and difficult for others to understand. There was no design methodology and indeed the models 'just happened' or 'emerged'."
