[Ken Maltby]

One thing to keep in mind (if you don't "De-DRM" your eBooks), is that the downloaded
ebook file remains keyed to that particular Credit Card #. So if you end up wanting to
read the book on a different device or reinstall the book on a device that has been
updated, you have to use that same Credit Card #, even if you have a new card.
It can become a case of having files on your hard drive that unlock with old Credit
Cards, that you may not remember the #s of. You can have a new card's #s apply
to all the ebooks in your bookshelf on the purchase site. That would mean that you
need to re-download any of the old purchases to be able to unlock them, with the
new Credit Card #.

The current method of liberating .pdb has you use the proper Credit Card # in the
process of creating an HTML structure without DRM. You can then use Calibre to
render that into the format of your choice. (ePub is a good choice for the JBL)

So, if you want to be sure that you can always use the eBook you have paid for,
either store the real Credit Card # for that particular book, with the book -or-
De-DRM the eBook.

Luck;
