Heya guys.
I have little experience (not ownership) with epaper. Only saw 3 devices:
a 10+ year old amazon kindle
paperwhite 4
some old pocketbook
I liked the pocketbook most and both kindles seemed similar despite the age difference.

And since I first learned about this technology I was sure I would buy an ereader some day.
However, I have this defect called perfectionism. I wanted the device to be of perfect quality and last for decades. Now as I'm aging I'm realizing that may not be viable and am willing to make a compromise (instead of continuing to have NO device at all).

I would love to hear your suggestions with these guidelines:

Nice to have's:

*No WIFI
*Open source/hackable/changeable OS
*Lots of settings is nice unless the device is very minimalistic and balanced
*I prefer systems that have their firmware updated, instead of "released and forgot" by the manufacturer. If it is possible to install a custom OS then of course this doesn't apply.
* I would like to use the device in paranoid mode. As in, I wish to never use WIFI, if it's there. So no downloading/buying from stores or libraries. Just simple PC-to-ereader transfers strongly prefered.
*nice and cozy orange light is <3
*Doesn't have to be comfortable to use. I don't think I will care much about button placement or lack of buttons or whatever.
*Good battery/Good battery time
*Removable battery is probably too good to be true? I would like to be able to change it in 3 years or so.
*Basic PDF support is big plus. Got some journals to read. No need for anything special in this regard.
*A good quality sound chip for audiobooks and music would be a very nice addition
*disk encryption
*I want to feel and know that I own the device after purchasing it and forget who made it
*Ability to write notes using onscreen keypad/keyboard would be a nice addition but definitely not must have. I have hands of an MD so stylus is useless.
*Preferably highly power efficient hardware. Don't care about speed at all.
*No bluetooth or SIM capability, if those are even 'a thing'.
*Preferably no loudspeakers, no SD/other card slots.

Must have's:

*Not Amazon
*Not bound to a single ecosystem. Shouldn't demand registration, or require internet connection. No ads. The device should wish to serve me, not limit me. Shouldn't be intrusive in any way.
*Good build quality. I want it to last for years. I understand even cheapest plastic sheit could last a decade, but still would love to have something made with care and quality components. Preferably sturdy built but not necesserily.
*6-9 inches. So I suppose medium/standard size more or less. Portability is not a huge priority. Doesn't have to fit in the pocket.
*waterproof/dustproof
