I work in a public library and I take out ebooks on my tablet because I just find it easier and more convenient despite the oftentimes higher cost for my library. If ever I forget to bring my iPad to work, I can still pick up where I left off on my phone and whenever I finish my book, I don't have to make an extra trip or wait until my next workday to start my next read. I looooooove ebooks. But that's borrowing books.
If I'm buying it, I like to actually own the book and be sure that in 5 to 10 years, I'll still have access to it. If they were selling DRM free or even watermarked PDFs, I'd be down. That's why I like https://www.leslibraires.ca/
for French ebooks, because they often
offer exactly that. When I recently bought Assimil le coréen, I did consider the e-méthode, but opted for the print copy in the end. I'd rather have a PDF, the audio and my handwritten notes all on my tablet, but I don't like idea of one day losing access to the course I bought (if Assimil went under and their servers were no longer running or because the app is no longer supported by my newer device, for example), not being able to lend it to a friend, or not being able to resell it if one day I choose to part ways with it. I understand their desire to protect themselves from piracy, but a lot of their texts and audio can already be found quite easily online anyways and I don't know if the app makes it any harder for the pirates out there to do their dirty work...
All this to say: I love screen reading, but I don't really approve of the direction Assimil is going in.
