I recently started using an eink Supernote device in A5 size and it is really change the way I interact with PDFs. The best part is the software is native PDF highlighting and commenting and leave comments using handwriting recognition.
Unrelated to PDF I built a Supernote Obsidian plugin too.
What else about the Supernote changed the way you interact with PDFs, besides highlighting and handwritten comments? Does the form factor make a big difference?
Asking out of curiosity since I've been eyeing eink tablets for a while.
The main thing is reading long form PDFs doesn’t feel like a chore because it was hard to get comfy and just read without printing. And frankly I am not always near my printer when a paper comes up I want to read. A laptop or display just doesn’t work for me. Also, unlike print outs I can have everything just in my bag at all times.
The supernote is light and the right size so reading lying down, at the couch, or sitting on the ground works for me.
