My Astak PP (MRSDK based) chokes on a number of Apple
mandated things that many older EPUB devices never
imagined having to deal with.
<rant> EPUB3 is about Multi-media, not a traditional BOOK that has static images and text. Leave my books
alone!

I will use my EPUB 2 device as long as I can. It fits my hand with the BUTTON controls in the correct place for reading with 1 hand (the next page button on my K4NT is just a bit
off.
