Anyone who hasn't used Excel is totally out of touch with reality (constrained to developed world). Excel is counterintuitive to whom? What intuition does it upset? It's a grid of cells. Each cell can reference any other. You can immediately see the definition of any cell when selecting it. I'd wager that it's used as a presentation or modeling tool far more than as a CSV editor. Its dynamic aggregated views, what-if scenarios, charting and dashboarding hardly could be replicated with SQLite or CSV tools alone. Surely not as seamlessly or intuitively as Excel.
