Coda is a next-generation spreadsheet designed to make Excel a thing of the past (theverge.com)

Good luck with that.

Doesn't look like a spreadsheet to me.

It falls more into the space that are occupied by Podio[1] and Zoho Creator[2] - where you basically create small apps to support your business workflow.

Personally, I still don't like these web apps. I want something that run local. I am not sure if only runs in the cloud or will there be a local version or not.
