The B&N ereader software is not compatible with my Palm TX. Hoping that the books were your standard pdb books, I purchased one title and tried to download it to my Palm, since I have both Mobipocket and ereader software on it. Unfortunately, the title I purchased didn't load and one of the free titles loaded but would not open. Thus, it appears that B&N uses a proprietary form of ereader, which only their software will read.
I've been thinking about buying the Ipod Touch as a backup reader and to have access to Kindle (and now B&N) titles, but I was hoping the B&N books would be usable on my Palm TX, but apparently no such luck.
Looks like I may need to buy that Ipod after all (or a refurbished Kindle 1 for a slightly lower price).
