The cure for this is to convert them to DjVu. Files end up very much smaller with no significant loss of quality, and page turn if not instant, is gapless and smooth. OCR can be easily incorporated into the DjVu for text searching. PDF to DjVu conversion is pretty fast and easy with a number of free utilities.
The DjVu page turn speed is probably fast enough for music.
I've noticed that some epubs, commonly commercial ones, default to two column display when the font is below a certain size. This is quite a nice look for many books, like a newspaper or magazine layout. Epubs that don't have a suitable page format sheet in the Styles directory won't do this. It's pretty easy to add it in if you copy the relevant style info over from one book to another, and make suitable adaptions in the html headers. ("Book conjugation" this should be called, on analogy with bacteria.)

Yes but then you loose all the PDF annotations advantages that everybody is fighting for. Am I wrong? I am not a DJVu user.
I believe some of us, if not most, want to be able to annotate the PDFs and export them for further processing or to forward them to other persons
