You're assuming that the nook will support the same adobe encryption as the 505 used and can be authorized by the same account. Neither of which are known for certain until it's in our hands.
Backup and reuse of DRM'd files is a huge concern and definitely can not be trivially wiped away by such unfounded commentary. Other, more popular systems are even more impacted. For example, your files with amazon are good on one single device and useless to back up. Amazon does it for you sure but that's not a real backup. Furthermore, no new devices will support their encryption schemes because they aren't sharing. Furthermore, you can't move to another line of devices. You're stuck with Kindle.
With ePub you have a few more choices assuming that you get a common DRM format. eReader, same deal, but not MUCH better. There is no ePub reader for iPhone that supports any DRM, for example.
IMHO, this is the most valid concern about eBook readers. Life-long readers do not know this kind of limitation in any form. Lending books has always been trivial, and you've never had to worry about transferring your books to a new format unless you go blind or something.
eBook readers demonstrate epic failure in this regard, due to publisher fears more than anything naturally.
