Looking for input on eink devices, for ebook and writing. Primary use is to digitize my library. Writing will be mathematical in nature.
Current favorite: supernote (https://supernote.com/)
Current runner-up: PocketBook InkPad X
I value:
* Openness, OSS compatibility
* Interoperability
* Repairable, upgradable
Tech proficiency: long-time OSS native, I have FreeBSD laptops and servers, run graphene, etc., can fetch, modify, build, install OSS.
