Ah, you're right of course, I somehow missed "Library" when I did my forum scan. That would be a better place. Can someone move the thread?

Sorry, wasn't as clear as I should have been, Digital Rights free (so that you can put it on whatever device or devices that you own that you like), but not free in cost. The Kindle/Nook versions are cheaper but they restrict which devices can use them (unless one is a computer whiz and removes that protection, which I've never looked into doing).
