- Ingenuity (helicopter drone on Mars)
- Smart TVs and streaming devices (Samsung’s TizenOS and Roku devices)
- Smart appliances (Samsung’s smart refrigerator)
- Digital signs and billboards
- My car stereo (Sony XAV-AX6000)
- The Large Hadron Collider
- FAA Air traffic control and radar systems
- Self driving cars

tl;dr : if you want to try to hack it safely, heads up to : https://remarkable.guide/
If you would like to run a pre-made Debian chroot on it. Saw other distros from other users https://github.com/Eeems-Org/remarkable-debian-chroot
If you would like to use (Not fully replace for stability/recovery concerns) another launcher which is MIT licensed https://github.com/Eeems-Org/oxide
You can install the “vanilla” (minus extra bits) kernel via Toltec https://toltec-dev.org/stable/#section-launchers
Aaaand, if you want to go the full libre way, there’s a port of parabola on it sold here http://www.davisr.me/projects/parabola-rm/ Article here https://hackaday.com/2020/09/06/a-free-software-os-for-the-remarkable-e-paper-tablet/
