After the 3.1 upgrade I bought one book from the Readerstore in the new Epub format - no problem. I had to re-enter my address and payment information one more time though.
Looking for "Pirate Latitudes" without finding it on the Sony place I went ahead and bought the book from Books on Board. Even thought it said I needed Adobe Digital Edition (which I installed) it never seemed to use it. As soon as I downloaded the purchased book it popped up in my Sony eBook Library and I could copy it to my Reader. I noticed the font was for me somewhat small in "Small" so I enlarged it to "Medium" and it looked great on the PRS-600, filling the screen almost to all edges.
Btw, being a non-native English speaker the dictionary is a gift from heaven. I wish that Sony in the future could make dictionaries available for other languages as well (Like English-Norwegian) but the Oxford English is of superb help. While Norwegian has about 40.000 words, English has maybe around 200.000 thousand words.
