I'm not sure if this has been covered, but these are my two cents. You can use the Stanza application on a Mac to download protected (Secure) PDB eBooks that you purchased from Fictionwise/eReader. You can then transfer them to the Stanza app on an iPod Touch, iPhone, or iPad via iTunes on the Mac. You can read them on the Mac or on the iPod Touch, iPhone, or iPad. You'll find a discussion of this at lexcycle.com web site,

Unfortunately, you cannot transfer these files to the new nook. I've tried everything I can think of as have others. B&N doesn't seem to care, but at least if you no longer have your Palm device, you can still read your Fictionwise (and eReader) eBooks on some new devices. Hope this helps some of you.
