I don't think most consumers have really thought the whole thing through. Anecdotally I would say most people don't back up files without DRM, e.g. digital photos. I'm sure for everybody reading this comment it seems really obvious that you would want to back up your photos. If the average consumer doesn't understand the very real possibility of total data loss and losing all of those photos, why would they even consider the downsides of purchasing and downloading e-books onto a single device? Granted I'm mostly playing devil's advocate here, but I think it's entirely silly to expect people to know things that are very firmly technical knowledge and not common sense. The person you replied to might have known that their eBook reader is prone to failure but what about the vast majority of consumers?
