That sounds suspiciously like a halfway house for fixed-format.

With epub3 you should have popup windows in any ereader that supports the protocol.

That still requires the ereader provides support for this, specifically. The most you can say is that now there is a meta tag to describe it, we might see more devices/apps implement it... but it's not like it used to be hard.

Once again -- popup footnotes are a feature of the renderer, not the format. If the renderer doesn't support popup footnotes, EPUB3 footnotes won't help. Especially for EPUB2. But if the renderer supports regular old link-based footnotes, they can do the same with EPUB2 as well.

There is no real functional gain IMHO.

Yes, of course. Please, read this thread:

Also css3 allows elements to be styled in various shapes (i.e think circle divs) and you can wrap your text around the edges of a curvy design. Please, read these articles:

Also you can have text-shadow, hollow text (text-stroke), text in perspective, text reflected, etc., etc.

Thanks.
I agree that does look pretty interesting.

With javascript you can change the layout of any epub ON THE FLY; things that are ok with some font-size, they can not be with a new size. Read this thread:

Now that I simply think is a bad idea.

Of course you have the right to sustain your opinion, but with css3 you can do a lot of things with less (much less) code. You can style chapter titles and to use layouts in a way not possible with css2.

I don't really have anything against CSS3 per se, it's the idea of javascript in ebooks that gives me the willies.
