Distinguishing ebooks from apps
Closing the gap between HTML5 and EPUB 3 support
I believe this statement by Bill was one of the most important ones in the whole discussion:
As EPUB 3 proliferates, there’s no reason for EPUB 3 support to continue substantially lag browser support.
That lag is one of my biggest concerns as well and why I feel publishers should focus on HTML5 itself and not something else that’s built upon HTML5 (and therefore requires more time for development and adoption).
What’s your opinion? Will the gap between HTML functionality and EPUB reader support for those features shrink or will there always be a lengthy delay in the latter’s ability to keep up with the former?
