I think Engadget has it's facts wrong here... or I do? This http://www.engadget.com/2009/10/25/s...ook-with-epub/
article boldly states:
The ePUB standard, developed by Adobe, allows consumers to purchase books at a variety of digital stores and use them on a wide range of compatible devices without the manufacturer having to explicitly support them.
Of course the Wikipedia article on ePub http://en.wikipedia.org/wiki/EPUB
doesn't mention anything about Adobes involvement.
I personally think the the author of the Engadget article is a bit confused. Adobe developed the Adept DRM wrapper and a mobile reader device SDK and encryption server product which packages ePub (and PDF) files.
Do people feel that this confusion over the ePub format verses the Adobe DRM isn't going to confuse people. Heck, if Engadget is confused, how is the lay person not going to be.
If I am totally of base on this, perhaps I am the one that is confused.
