OK, thanks for the explanation! So for epub books then the Sony upgrade is fine, but why the big buzz about ADE and Adobe's secure digital pdf's. Really mostly useless for me anyhow! However, I would want to be able to buy books in that format also, if they were formated in a correct way. Public domain books are fine, but I still buy a lot of new books through Connect, and the good thing would have been if that could be expanded also to other sources, but not yet, so for some reason the upgrade will still give Sony my book buying money
