600/170 = 3.5294117647058823529411764705882
So, I figure the screen must be pretty close to 4.7 inches by 3.5 inches. (That's 11.9 cm by 8.9 cm for you metric users out there)
As a cross-check, I plugged that into the Pythagorean Theorem, and got a calculated diagonal measurement of 5.86 inches, which is pretty close to the 6 inch diagonal that Sony reports.
Unfortunately, I can't get a firm read on what the best size would be, my information suggests that the font sizes in the original document make a difference, and that you have to play with it a bit to get it just right.
However, I think that the screen dimensions give us a good place to start. If we made a PDF with 4.7X3.5 pages and little or no margins, that ought to be in the right neighborhood. We'll just have to tweak it once one of us MobileReaders gets some hardware to test on.  |
He he I made a calculation mistake with my 16.93 but ok. :P
Anyway, the iLiad has a resolution of 1024x768 but part of that is used for the iconbar. If you say that this is not the case with Sony that would mean the Reader screen is even bigger than described since the 800x600 is for user use. I think that indeed we just have to wait till we have a Reader in our hands. For the time being I'm collecting my ebooks on .doc format so I can go all the ways.
Damn Sony bring that Reader out so we can play, play that is!
