The new Codexes are in a fixed layout format, and only certain readers seem to handle them well (they have recommendations on their webpage). If you are really attached to a certain reader program then you might be disappointed.
On my PC they work well using Azardi. On my tablet using Gitden the font scaling seems to be wrong, and while still legible they aren't as convenient to read as I would like.
