You can easily convert other formats with the Mobipocket Reader for PC (just import them and it automatically converts to PRC). Some PDFs can cause problems on the CyBook, but if it's just eBooks (not documents with lots of pictures and tables) they convert nicely.
The fonts need to be put in the Fonts-directory on the CyBook (if you want/need to have italics and bold styles, you need all 4 different files for each font). If you want to try: I'm using Goudita Sans SF which you can find HERE
