a) It wasn't me it was LuBiB posting those pictures

b) guessing dpi doesn't seem very accurate

c) why not just calculate the dpi of the jetBook Color?

It's got a 9.7" diagonal screen. We know the screen aspect ratio 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.
