I would agree. I'm an Apple Numbers user now but I have yet to find something even remotely as useful as the spreadsheet abstraction. I use them for everything from solving engineering problems, forecasting, statistics, decision analysis to personal finance and project planning. I could solve all of the problems with a programming language but it'd take 10x as long.
