You are wrong in this post.
The colloquial definition of a spreadsheet app in about 100% of the world at this time is the ability to do calcs.
This video is fantastic, but what shows is currently purely a layout app (hence the grid nomenclature) - frankly - it is a visual Workflowy.
Also, you know what is a drag on innovation, lack of cordial discussion (I am a perpetrator of this myself - even on HN, I get emotionally involved in something and it takes another HN user's response to give me perspective) - and I think you were harsh in your comment, and rather than foster discussion about this, you attacked the OP.
I am sure all of us agree with: "I think most people agree now that it's valid strategy, particularly in software, to launch a simple version one of something and then iterate rapidly"
But I found nothing snide in the OP at all.
