I signed up to ReMarkable during the beta/pilot announcement having gone through decades of testing Palms, iPads, eReaders, pen scanners in search for that analog experience.
I didn't pull the trigger after the early adopter review having seen so many of these devices rushed to market with half-baked file i/o or UI issues with crippled hardware/software slowing that "pen/pencil and paper" experience down. This marketing desire generation is usually coupled with amazing incredible first impression reviews https://youtu.be/RGsWLeHZT8Y that only scratches the surface of total ownership experience.
So far the iPad with Pencil has come closest but who wants to lug that heavy thing around?! From my experience, customers really have to buy the company/platform not the device in hopes that they have staying power. Remember Livescribe? https://www.youtube.com/user/nevermissaword/featured Well they're baaack ... again.
I can only hope the best for ReMarkable and that they sustain the ecosystem to continue on with "your" notes. +1 for the open source we direly need it and that may be enough to support them and buy their 3rd gen model.
Currently I'm really enjoying analog fountain pens and paper, although more expensive! (14K nibs with custom grinds) they're pros on interface pleasure, offset power consumption, privacy and well ingrained UI. Search is waay slower but it helps brain power.
My later tech bet is on paper journal digitalization like Google Books with data capsules: https://wiki.htrc.illinois.edu/display/COM/HTRC+Data+Capsule
and doesn't everyone use MyScript API for handrec anyways? https://developer.myscript.com/ or more openly I'm hoping on improvements to the tessaract pipeline: https://github.com/tesseract-ocr/tesseract/wiki/ImproveQuali...
As for current digital solutions, sadly it's going to the big gorillas via market share like MS with Onenote, or Google with chromebook tablet https://chromeunboxed.com/chrome-os-78-tablet-mode-ui-overvi... (termux Evil Org-mode with your fav Android pdf reader for papers!?) and Apple iPad pencil. Does it have to be this way? It would be ReMarkable if they can pull this off!
