Beautiful site, beautiful notebooks, totally incorrect slogan.
It’s not a notebook that “syncs to the cloud”. It’s a notebook that is ARCHIVED to the cloud. You can’t access any of your notes until you send it to them, ostensibly when you’ve filled it up. So, instead of it sitting on your shelf with other notebooks, you can have it archived to the virtual shelf in the sky.
THAT’S NOT SYNCING, THAT’S ARCHIVING. Yeah, it’s a handy feature, but it’s not how they are selling it.
