I like having good coverart. I don't understand why a purchased ebook comes with a generic cover. If they can take the time and expense to make a nice cover for a hardback edition, why can't they paste a simple jpeg into an electronic one?
I think ebooks are where online music sales were 10 years ago. Early music sales were crippled with DRM and the quality was poor (128kps). Now they sell music DRM free at 256K. Now, early ebook sales are crippled with DRM and often of poor quality. No coverart and poor formatting.
The music industry is finally listening to consumers (or reacting to pirates). Will the book publishers start to listen?
