KOReader: a free electronic-book reader for e-ink devices

I don't have a lot to say about the DRM stuff. I more or less disagree with that model in the sense I think in all practicality it will be removed by pirates but will stop non-savvy users from sharing with friends, which I think (as long as it's only one level) is fair. Of course, whatever terms the author decides, the author is free. But:

> funny enough, digital sales seem to be lower than physical sales

Having streaming services available this actually doesn't have a real "funny" factor if you think of it. Except from some more conscious users that may not entirely trust streaming services to keep all titles up (it's happened before after all), the only people that may be interested in actually having a copy are proper fans, the kind that would value the boxing art the copy comes with. For example, I don't own a lot of shows, but I did buy the Lost box set back in the day, because it was damn beautiful and very elaborate. A digital copy would have been meh, even without streaming services piracy isn't really all that prosecuted in my country and, while nowadays I'm wary of pirating something I can pay for and I appreciate (I like to incentivize authors of stuff I like), at the time it seemed like a waste of money. I didn't have a lot of money back then either, a lot of savings went on that box set.
Most users would rather prefer the practicality of streaming.
