My dad is an accountant, and I distinctly remember the day he used his first spreadsheet program. It was the “killer app” for those in the financial profession. You would think he had just won the lottery.
He went on and on about how it made his work—and life—so much easier. Spreadsheet and word processing programs were the bread and butter of computer software packages in the early days. Now, of course, you can get software that will do just about anything—even your taxes.
