For me, cloud computing means that my changes are instantly backed up in the cloud, and instantly available on any device that accesses that cloud. It eliminates any individual point of failure, so if my tablet disappears, the work is still on my laptop, etc.

Doodles in this notebook are neither backed up nor accessible anywhere aside from the notebook itself until you've sent it in (at which point all your notes are inaccessible for a time during transit). This is a document scanning service either banking on a current tech buzzword, or based entirely around a misunderstanding of the cloud.

That's not to say it isn't a neat idea, it just has nothing to do with cloud computing.
