IorPerry, please try to keep a respectful tone in the forums!
If you only came here to blow off some steam because your Cybook does not work like you expected it to, that is ok, but if you start insulting other people because they answered to your rant in a similar way there is a good chance this discussion might get out of line.
If you came here to get information and some friendly advice, I cam promise you there is a lot to be found in these forums - and I can asure you that users like netseeker, who does not own a Cybook himself, can give you a lot of help on the topic aswell.
Most of us who are into mobilereading and e-ink devices for a long time now, took a lot of effort to compair every single device out there to compair it to our own reader.
Hence it doesn't really matter which device we own, we are pretty familia with the good and bad of the others aswell.
So to answer you questions:
A complicated PDf like the one from nvidia is indeed a lot of work for a small device like an e-ink reader. I've also tried to open similar documents on a palm and even if it succeeds it takes a lot of time because most pages consists of several images that need to be resized - what takes a lot of computing power.
You will get better results with documents that constist of a lot of text and a few pictures in between.
Additionally there is the problem with the screensize that requires you to watch the pdf in landscapemode to be able to read anything.
For these complicated documents, if it's inevitable to read them on the Cybook, I have found it to be a better soultion to use a program that creats images of the pages.
These programs take the pdf document and break one A4-page after another down to one to 3 landscapeimages, allowing them to be read quite comfortably.
Another way would to convert the files to mobipocked format, but documents like this one are bound to be a lot of work to get an acceptable result and unless you want read the document over and over again it's probably not worth the effort - if you plan to use it on a regular basis you might consider it anyway.
The empty text in you specific document is caused by the fact that PDFs can come with special fonts embedded, but can come without the embedded fonts but still require them. That's the case with your document - you will have to find out what fonts are used in the document and install them on your Cybook - after that, the PDFs should be displayed correctly.
