Hey, have you considered the supernote A5x ? It is a great device to annotate and you have more options when it comes to import/export. I have both, remarkable is great to mimick a blank page but to organize knowledge and reading, supernote feels better to me.
Especially because you can automatically search your handwriting as it recognizes it in the background. Eye strain is an important factor, so you’re really right considering a eink machine !
I felt the same way, until I discovered It was not easy to carry the remarkable everywhere for (partly irrational) fear of breaking it. The supernote is all plastic, it was definitely a plus.
In the hands the supernote definitely has a charm, it doesn't feel like a random tablet either.
