Which ebook formats—if available, of course—do you prefer to read on your jetBook?
In my experience, epubs and fb2s are the best, in terms of conserving an ebook's original design and formats. New chapters can start with a new page, empty lines intentionally separating paragraphs are not omitted (as in many rtfs, txts), and all images are present.
Some htmls have these characteristics, but unfortunately not all. Also Mobis and prcs files are OK sometimes, though not always.
Producing a fb2 file with BookDesigner is really easy. And the word processor Atlantis (

A pity that none of these formats work with hyperlinks!
