Well, I think the covers are still important. Granted, the description I'll only read to find out what the book
is, but covers are how you recognize the book when you see it. It makes it easier to recognize your books on your bookshelf/eReader, and a lousy cover is very much noticed. In fact, there is a stupid trend among publishers --
especially Penguin -- to replace the cover inside the actual book file with a generic ugly cover. Penguin goes one step further and shows you a picture of a penguin -- really helpful, isn't it?
Lots of people are bothered enough by that that the first step for reading the book is to change the cover with calibre. See
this thread, which evolved into this discussion. The suggestion was offered that people should make a point of returning the books for a refund and giving feedback on this.
In other words, covers are
important!!!
