It's got a 9.7" diagonal screen. We know the screen aspect ration is 3:4 (1200:1600) so in those numbers the diagonal length is 5 (it's a 3:4:5 right angle triangle). (9.7/5) * 4 = 7.76" screen height, which at 1600 pixels gives 1600/7.76 or ~ 206 dpi.
So your guessing was pretty accurate after all.

I would rather believe in numbers like above than in pictures
However the above calculation starts with the assumption that the resolution is 1200:1600.
I would still like to see the PDF that has color highlighting on it in a picture side by side with an A4 paper with the same image. Since I have not seen how the ereader displays such a PDF I can not entirely trust the numbers above.
In pictures M92 (which I now proudly own :)) ) looked OK in portrait mode. Now that I have it in my hands I know that it is usable just in landscape mode for reading scientific or technical papers.
