Agreed, was coming in here to comment on as much. I don't think anything on the demos really stood out quite as much as the grid forms does. It's closer to what people who might be replacing a paper form would probably like.

Whenever I'm designing a system that is replacing paper, though it's been a long while. I find it best to start with as close to the paper version as practical. There's a lot to be said for making something that is familiar.
