I have observed a strange/alarming behaviour when I carry a notebook - because friends and family don't typically have one, they find it intriguing and so will sometimes absentmindedly snoop through what I've written if I leave it unattended. The same thing just doesn't happen with a ReMarkable (and even if it did, you can set a PIN code).

I'm glad I'm not the only one who experienced that! Such a fascinating experience, though really quite upsetting at the time. Doesn't happen now with my PIN-locked e-ink device.
