I appreciate the help of everyone, at least maybe I am headed in the right direction. Let me run over some things to make sure I have this clear. Please correct me, if I have something wrong.
I can download Calibre, then buy ebooks from any source, be it Amazon, B&N, Google, Sony, etc….? Use the Calibre to remove the DRM, then I would be able to download the book to any device I choose, be it a Kindle, Nook, Sony Ereader, Samsung Tablet, etc….?
Now, along with that, would I have to have them delivered initially to my computer, then transfer them to the ereader or could I have them delivered to the ereader, then transfer them to the computer to use Calibre, then transfer them to any device, I choose?
Having removed the DRM, I would also be able to save them to an SD Card, Hard Drive, etc…. and keep them from now on, loading them onto any device I might have in the future?
As far as the Adobe Digital Edition, how exactly does this come into play? Is that what then allows you to transfer it to different devices, after removing the DRM?
Again, I do appreciate the help.
