There's a lot of info, opinions and screenshots on viewing pdfs elsewhere in this forum. I prefer to use my iLiad for larger pdfs. I've loaded the same pdfs on a Cybook, iLiad and HanLin to compare them. I believe they display better, are more stable and easier to read on the iLiad - partly because of the larger screen size, of course.

Note that the e-ink screens on these 3 devices look very similar when side-by-side viewing smaller pdfs or Mobipocket files.

Unless you load 3rd party programs on an iLiad, pdfs aren't bookmarkable or searchable.

You can look up all definitions of a word in a Mobipocket dictionary loaded on an iLiad (my dictionary's on a CF card). You use the stylus with the onscreen writepad/keyboard to enter the word.

You can handwrite the translation of "I park here allow?" easily onscreen on an iLiad.

I'll think about your questions a bit more - I might be able to add to the above.

OK, here's a screenshot of a lookup in Webster's 1913 dictionary, which you can download here at Mobileread. Click on lingo with the stylus to view the definition. (Note the iLiad screen is not as black and white as my screenshot, but it is very clear and easy to read)
