Calibre tends to do pdf to epub conversion as a series of png image files (one per page). While that makes the resulting epub file viewable, you lose the ability to zoom the text or search for words, etc. A better solution is to go pdf -> html or pdf -> text, then use Sigil (http://code.google.com/p/sigil/ http://code.google.com/p/sigil/) to make an epub file.
