Regarding spreadsheets: Excel (and similar) is a great toy for doodling, but for serious work one would want the 'real thing'. In the 80s there was Javelin Plus, then Lotus Improv in the 90s. Now there's Quantrix. With endemic spreadsheet errors (since the 80s), and far better solutions being ignored (also since the 80s), there's certainly something to rant about! ;-)
