Although I do have colour on all the pages of the books I read on my colour e-readers, not just on the covers, I understand that a colour e-reader is only interesting if you really want colour (for whatever reason, which can vary greatly). If colour doesn't add anything for you, I don't see much point in it. But if you want colour, obviously a monochrome e-reader isn't going to give it to you, no matter how excellent its monochrome screen is. Perhaps in this sense, the results of the opinion poll published in Mobileread on the preference for one type of e-reader over another are understandable.
