Just so I could like sync a channel, for example, download the current available and upcoming videos so it could be accessed via Jellyfin (or something similar, or maybe upload them into a locally restricted hosted PeerTube) locally?

I have been wanting to have an e-reader so I can stop piling up physical books (takes a lot of space) and im not sure if i should straight buy an e-reader (do they have programmed obsolence issues too?) or an affordable and durable netbook/notebook/tablet
