Hi chaley,
yes, I agree that the list of features is impressive, sorry if it sounded like I didn't

And the cloud connection is a **very cool** feature, definitely worth the price of the app by itself.
Having said that, it is still true from what I understand that CC builds its own library, it does not use calibre's. I still find the app description misleading, but YMMV of course.
Apart from linguistic opinions, could you maybe suggest the most efficient way to keep a relatively large calibre library (~5000 books, 10GB) always sync-ed between a computer and a tablet? One-way sync (from pc to tablet) is really all I need: I don't expect to be ever editing the library from the tablet.
Thanks for your help,
Andrea.
