That's cool and all, but I generally prefer my text reflowable, and find PDF reading on any not-huge e-reader to be a pain in the ass. It's worth it for things that are rich in figures and formatting (like House of Leaves, many textbooks, comics and manga, etc), but for the typical novel or non-fiction book, I really do want just text and the most minimal formatting and layout instructions possible, so I can configure to my own comfort, not to whatever the publisher has decided they want me to see.
