Just for interest, the calculations in my business book "Nukenomics" (published April 2008) were all performed using an HP 12C and an HP 42S. I have credited HP in the preface to the book, although with the popularity of XL these days I do wonder how many analysts under 40 will have heard of HP calculators or RPN.

Best wishes
