Same here, though I recently got a reMarkable 2 to replace my paper and love it more than I could have imagined. It’s a magical device for me (no affiliation).
That is the main reason I’m thinking about an electronic replacement.
I decided to return mine and the entire process took nearly 2 months.
If you buy one, assume you will never get it repaired or return it and that you’ll either keep it forever or buy a new one even if you’re under warranty.
My experience, would not recommend. I’ve heard better things about Supernote.
For ‘thinking process’ specifically, I think it’s the ability to have unlimited notebooks in one device. Often while writing notes for one thing I’m inspired about something else, so I can quickly switch to that notebook and jot it down.
