My post on my drupa blog is more about Acobat X
Don't get me wrong. I like video, I like animation. But my interest in text and flat graphics can get a bit of a tight focus sometimes and it seems clear enough now that PDF is a finished work. Wrapping it in Flash is not very interesting from my point of view.
Probably detail on print etc will be in the drupa blog. The design on the IPEX one is old and no headline shows up.
