An Excel-lently well done product [Links]

I spend most of my work day - & quite a lot of leisure time - on Microsoft's Excel, A product that has its origins in Lotus-1-2-3. Dan Bricklin, the creator of VisiCalc, which was then pushed out of its numero-uno spot by Mitch Kapor's Lotus-1-2-3 shares some very interesting thoughts on its 30th anniversary, on a product that holds most of the world together (Doubt that? find out what your company uses to do any analysis!) He shares some rare footage from the time too (no one does the dance moves any more though!!)
