On the other hand, if it is the so called "kePub" format then no; you can't do diddly with it.
I find that if I add a book I bought through the Sony ebook (borders) site, I can not read it in the Calibre software due to DRM. Nor get the cover and other info. Is there a way to download it directly to Calibre? Or with the PRS-900 to buy it from the wireless device and then move it into Calibre?
