You can make a shopping list in Excel, and you can also run a $100M+ company with it. It's probably the most important and powerful product Microsoft has made, right next to Windows itself. Anything taking on Excel would have to be able to do all that, while also offering so much more to overcome the friction of switching.

Otherwise it's just a niche product, which is still valid, but not really a next-gen spreadsheet. Coda seems like it would be great project management/CRM tool rather than a spreadsheet app.
