I'd also worry about bugs accidentally inserting bogus data into it. The author says he doesn't like spreadsheets because of all the copy and pasting, but I think that's a feature. You go over every calculation to make sure it's right, and once you have a template sheets to copy and paste for a monthly report or something, you're able to do a lot less of that. It can be hard to view a raw database to track issues down depending on how it's structured. Usually you need more than viewing tables as spread sheets at least.
