Based on the screen dimensions that TaKir
measured for us (assumes the Sony screen is, in fact, the same size as the HanLin V8), I came up with a "well, duh" WAG
for pure text PDF pages: 3.54" by 4.84" with a .03" margin (90mm, 123mm and .8mm, respectively). But we won't know how well that will work 'till we have one to play with.
For your manuals, bingle, first I'd like to comment that the idea of putting D&D manuals on an e-ink reader has an incredibly high NQ (Niftiness Quotient).
Since we know how the native Sony PDF viewer will handle zooming PDF pages, I'd say that if you can crop the margins off, and use the 90° rotation feature, you'll probably end up with something somwhat larger than half sized (assuming an A5 size on the original pages), that will display in 3~4 sub chunks as you scroll down the page.
Of course we don't
know how much control the rotated function will allow for scrolling -- will it allow you to scroll down as far as you want to, or only in pre-sized chunks? The former would allow more of the material to be useable than the latter; most diagrams aren't much use if you can only see part of them at a time.
At a guess, some of your files will work okay this way, and some won't.
On the other hand, the OS is
linux (rather like the iLiad's), so homebrew viewers are pretty much inevitable, and who knows what tricks those might do for us? Especially considering that Sony doesn't have an IDS that effectively controls what apps might get put on its device the way iRex does at the moment -- and ain't that
a kick in the teeth?
I think that a lot
of material that we traditionally use is going to simply be useless or really suboptimal until someone puts out an A5 sized e-ink reader. (shrug) The present and presently pending devices are mostly aimed at pure text reading, the Sony definitely is, and they should do that quite well. I guess we'll have to decide individually if they do the other, fancier stuff well enough to work for us. I just want to read books, myself, but I think that an A5 format is likely waiting somewhere down the road, waiting to see how these first three offerings do. It'll probably pop up in the corporate world first, I suppose. But I digress.
