I doubt that many people are reading ebooks in a context where they need to copy and paste regularly, I could be wrong though. I read exclusively ebooks and it hasn't ever come up that I remember. I'm not saying it isn't a valid use case, but I question whether it is a common use case for the average user.

I'd be curious to know how someone has narrowed down the black box that is Netflix to determine that buffering is caused by the DRM.

Sorry if I was not clear, I suspect that DRM caused the buffering issue, or at least an open source player could be implemented that could keep more back buffer so you can go back 30 seconds. Wouldn't be illegal to reverse engineer the players that include DRM? or you would have to be careful not to look at the bytes that implement the DRM.

The Kindle and Nook iOS apps both let you copy/paste. I did it all the time when I got stuck having to use DRM ebooks in school, and never had a problem with it. There may be limitations on how big a region you're allowed to do it with, but, if so, the limit's large enough that I didn't encounter it in the course of normal academic use.

I did sometimes run across ebooks that basically used images of the text instead of actual text, and copy/pasting from those naturally doesn't work. But the ebooks in question were all non-DRM.

I am disabled, I need to copy paste the full chapter so I can have my Text To Speech application read it to me. Maybe today the Kindle app has TTS, I can't find it on Google though.
