Okay

Comics:
Doable. Not great. Screen is still just a bit too small for vertical use, but horizontal works fine. The method I was using is a PDF, I imagine a purer format one might get out of Calibre would be much better. But currently that's not an option. The grayscale looks great, but text is often to small. The vertical didn't seem to crop the white edges like the vertical.

Magazine:
I scanned (very high quality scan, mind you) a few pages of a standard glossy. Text is again too small for vertical use, but horizontally it is very readable.

PDF text:
Tried a number of these. One had a standard 12pt Times Roman font. A BIT too small on the screen vertically. Horizontally was about 11pt and very readable. It also leaves a bit of the last page up top so if you're cut in the middle of the line you're fine.

A smaller PDF that actually got enlarged a bit with the screen was very nice and very readable.

PDF tables of contents do NOT work - and that is a big pain in the butt.


Badly scanned PDF:
I scanned a few pages from a book - two pages showing. Unreadable in horizontal, too small. When turned it tried to be smart and just show part of page but you hit next and you'd get lines, etc - boy... this is hard to explain. Okay... Included a screenshot (first one)

Scanned journal article:
Single column - looks great

Digitial journal article:
wonderful

PDFs, text and scanned - were often very slow to change pages (sometimes as long as 5 seconds - and this file was only 4.6mb)


(I'll add more as I do more).
