Well... While I admire reMarkable in technical terms, I'll not buy a black box where I have to hack the box just to manage my system. I do not care much about handwriting recognition and other "cool solution to help the end user", I do care about no eye strain reading of LONG damn documents, where scrolling distract instead of help, and casual ability to draw things. Period.
Unfortunately they took a classic commercial path, maybe fueled by many "users desires" described by users who have not much an idea about how they can use such devices and the result is well... Not exiting especially for the price. I have no issue paying something I own, I do not pay for something I can only use.
No, in plain filesystem access, mounting it like any other file system on a mass storage, putting there my pdfs, pulling them back etc. I do look for a simple pdf/ebook reader with e-ink display large enough to fit A4 without zooming back, with essentially the same features of Evince/pdf-tools and so on. NOTHING more, nor less, nor with extra layer of complexity for commercial purposes.
Nothing* does mass storage these days, because you a) don't want to run your filesystem as FAT32, b) have two devices mounting one disk at the same time.
But anyway, you don't have to hack anything, they literally give you all the access you could ask for. Run samba on it if you want.
* I'm sure there are exceptions, but they're not common in my experience.
I have no issues mounting Linux fs, since my OS...
> have two devices mounting one disk at the same time
There is exactly NO reasons to allow mounting when the device OS is shut down and there is non reasons to not allowing mounting a data only volume who can be balanced read-only on one or another side. It's simply an arbitrary choice.
Anyway, as far I know their OS, a custom GNU/Linux distro is open in the sense of the license but I even need to host their own "fake cloud" just if I want a no-someone-else service needed setup and the unofficial repo is not much more exiting https://toltec-dev.org/stable/
Being open to me does not means "hey you have the code" like AOSP, is being damn open EASILY, the device is mine, I handle it as I handle a desktop computer.
