Have you tried a black reader, to see if it really does make a different for you, as a matter of interest? Please don't think that I was "just being contrary" - this is an interesting topic; different people do have very different perceptions of these things. There was another thread recently in which someone was arguing against black devices because they felt that it lowered the screen contrast (which I also don't find to be true, myself).
