You’re not missing anything. iBooks is what every EPUB reader needs to copy.
Well, if you say so, then it must be true !
Thanks for the reassuring thought that I haven't lost my wits. You mildly mentioned ADE before as a "less stellar" reader, but in this way, ePub 3 FXL will not fly...
So coming from InDesign, we have lousy interactivity in PDF, expensive marketing craziness in DPS Folios, overly flawed ePub 3 FXL readers on anything but Apple devices ? And in the meantime InDesign is becoming more and more monstrously wrong and even misleading in being clear on which interactive features fit into what format. This isn't a matter of required professionalism on the user's side anymore – this is a sheer lack of vision and execution on the developer's side.
I think after 5 years of wishing and hoping (and helping) Adobe to get these interactive media going, I'm going out of this messy business. Adobe is losing it. Digital Publishing as a derivative from these print workflow tools is not cutting it. HTML (for web or app) is the way to go, but creatively speaking, Adobe isn't very strong in that area either. Their development of such tools is too slow, and the results are too scarce.
"But we do have Photoshop in seven flavors !" – Really...
Sorry for the rant, but I'm gradually having enough of it.
