Actually, according to Adobe (
http://blogs.adobe.com/flashplatform...oken_link.html) the ipad will use a non adobe epub drm! Thus it is to be expected that other applications which allow the reading of adobe epub will be removed...
an excerpt:
"[...]Unlike many other ebook readers using the ePub file format, consumers will not be able to access ePub content with Apple's DRM technology on devices made by other manufacturers.[...]"
cheers,
