I know some people are having a hard time with Copia. And it sucks if they aren't helping frustrated customers. But I recently signed up again with my new laptop and I noticed two things.
1. You don't have to register with Adobe anymore. That annoying step is gone, at least for a new account/new computer.
2. I think they are doing something really interesting with eBooks. The Dracula annotations are really great. For anyone who hasn't checked out the free book
www.thecopia.com/dracula, it's worth it. I know there are plenty of other ebook sites out there, but how many are trying to take the eBook to a new level.
