I suppose we haven't really got the low down on Pages for iPad yet. The iPad Features page now has a bit more info but not a full feature list. However, that said, I'm surprised there has been no mention yet of EPUB authoring. I would have expected Pages for iPad (and desktop for that matter) to include templates and an export function for EPUB and for Apple to be harping on about it from the roof tops. Maybe I'm expecting too much too soon or perhaps it's not considered a mainstream enough topic to be marketing worthy at this point. I am currently playing around with Sigil and although I give 10 points to the guys for providing it for us it really is not an enjoyable experience at all to use (mind you I am using the 0.2.0 beta so that could be half the problem right there).
