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
More safe, imo, since at present nobody really bothers to try and use epub that way because it’s essentially only used for reading, and in apps that aren’t going to be able to do much in the way of escalating privileges. PDFs at least get used on a wider range of devices , and for more use cases.
