I think life without Word could be possible.
When I have to deal with a PDF book in A4 size, I usually try these ways:
- Using Acrobat to save as HTML 4.0
If it fails because of rights, of badly formatted text or whatever, then...
- Using FineReader 9 to save as HTML 4.0
The first one is the best because I get a perfect output (with an xml hypertext table ) but the second one is quite satisfying too though longer.
After that, I insert the HTML output in a specially designed OpenOffice model with Sony 9x12 cm format. Usually I have a little tweaking to do, like changing the main font to suit my habits (using the "Stylist" or F11 and right-click, then "modify"), checking these images bigger than the screen size...
Then I export it like a PDF and I modify the metadata with a special freeware program (not Calibre...) and upload directly to my Reader. I know there are other good choices for this last step, like using calibre to get an epub...
