I see that B&N are now
offering the eReader software with their own brand, but only for iPhone/iPod, Blackberry, PC and Mac. Seems like the Windows version is effectively identical to the eReader - it even has exactly the same README file, referring to "for eReader v. 3.0.3 for Windows." Not surprisingly therefore, it reads my .pdb files OK.
I assume therefore that I can continue to use the Palm reader on my Centro, and that the eReader file format will live on...
