I agree with you. I want to fully enjoy this great phone in all its glory. There is no phone out there that has a display as good as this one. Why pay for this and strip it of any of its beauty.
For those who can't see the difference between the highest screen resolution and the lower settings, it is understandable, because with a small screen, the pixels are smaller and the space between them are also, smaller making it difficult to see them. However, where you should see a difference with the N8's highest resolution is with the clarity of smaller print, particularly if the font is less bold or light. The edges of the tiny letters become more defined or less fuzzy or jagged, when you up the resolution. With images, their edges or outlines also become more defined, resulting in them standing out better from their background. They take on more depth, almost a third dimension.
(When I had my display set in FDH+ mode, I had to up the contrast to as easily read the same small letters, but this was at the expense of bolder headings and smaller letters underneath becoming too similar in boldness to be able to easily distinguish.)
