I use org-mode mainly just for note taking, and I've only been using it for a little over a year. In addition to notes, I do software planning and cost estimating. I prefer this to a "real" spreadsheet application, because they are mostly text, with a few important numbers. Those numbers can still easily be added to computations. Also, stubbornly, I prefer my comfortable emacs environment to the clicky unfamiliar interface of something like Google Sheets / Excel. Finally, org-export is fairly infinite in potential. I actually sync these notes to GitHub, which displays the org file as Github-Flavored Markdown -> HTML without even needing to export. The tables export very nicely, and are easily consumable in a read-only fashion by those who asked for them.
