You bought an Internet Tablet without first checking to confirm if there were document readers???

Here's my suggestions:

FBReader is an ebook reader that does a pretty decent job of handling my reference documents. The N800 also handles PDF pretty well, and seeing that I have Acrobat 8, I just have to make sure that it's compatible with older version of Acrobat, just to keep things simple and to prevent any new and unnecessary functions from choking the tablet

Your other option would be to get a Asus eeePC, which has document editing functionality which seems to be what you are looking for, rather than what you are supposed to be using an internet tablet for, i.e. on-the-go web experience for online reference, social networking, email, streaming video and music, offline video and music, etc, in a tablet form factor.

The iT, IMHO, is really not the ideal platform for document editing or composing large amounts of text, and the eeePC would be a better choice for that. However, as a mobile internet device / portable media player, it's more than adequate.
