I actually did look into the Evernote Smartbook when I had a look at the market & competition for this product. Looks really nice, but I think there's room for improvement & I have an idea or two. But first gotta get proof that there is a market for this
Haven't tried it yet, it seems to be just normal notebook, but with a special space on each page to specify notebook name and tags.
Evernote accelerator would be quite possible, maybe just build a rough app MVP for scanning close to what the moleskine one does?
