Thank you for taking the trouble to reply Cole, but I suppose I should have said that I have studied this Wiki (which is extremely useful) and the other very complete site quoted recently here, as well as reading a good many posts on this site. The basic "objective" information I am already aware of.
My questions about fonts and screen appearance, crispness of letters etc. are not dealt with in the Wiki. I would appreciate more "subjective" information on the screen appearance of the readers I mentioned and more information about fonts.
Is the rather mediocre appearance of the Sony screen performance due to the poor quality of the photos I have seen? But then why do the photos of BeBook and others seem so very much better?
Thank you (in advance) for more advice on this! Rojofo.
