Neat! I have one better though:
https://en.wikipedia.org/wiki/Post-it_note
* Works during power outage
* No battery!
* Very few remote attacks possible
* Very little attack surface
* Accepts multiple input technologies (ink, crayon, and so on)
Fair ofc :) This is more intended as a tech demonstrator and a bit of fun, although we have been using it for the weekly shop..
> Post-it note
* Produces paper waste
* Easy to lose
* Clutter
* Limited space
* Can run out of stock
* Not searchable/reusable
A gentle breeze from a running child unsticks any sticky note we have anywhere, how do you deal with that?
