An ebook reader from Framework would be awesome....

I would imagine battery life would be poor vs an eReader. In case you seek the same: I used a boox onyx (12"?) and OK overall. Issues IMO were the display is very fragile & did it in in the end despite a case and pocket in the bag, color was a bit of gimmick, most importantly the resolution was not good enough read journals/PDFs/stuff like the guardian weekly via libby crisply without zooming in... but the rest was decent. I switched to a kindle scribe I got for 1/3 the price after but it can't read the guardian or anything like that unfortunately like an android tablet. So just a bulky eReader with meeting notes there. If it even just showed my daily calendar I’d be happy.

This is probably close enough:

610 Euros seems quite steep for an eReader.

Boox Note Air 5C is €530, Kindle Scribe also in the region. Pine does tend to have a bit of a premium spec for spec, presumably largely from (lack of) scale.

Or a printer...

Or a phone ...

Or a router ...

No one will make a printer because the margins are so low. They are like the FMCG [0] of the tech world
