Correct. I link to the history of Topaz in

Yes, but only after a DeDRM tool/plugin converts the OCR portion to htmlz first.

Amazon tells you that your buying a drm book that will work on your Kindle or Kindle for ... application.
If you download the sample of the book you can open it up in a text editor to see what it is under the covers. Below are the first lines of two purchased books viewed in a text editor.
- TPZ0 cdictšVFPcdkey3
- Picking_Cotton KnoKnp BOOKMOBI
I've bolded the pertinent area that tells you which format the underlying book is created in.
TPZ0 = Topaz
BOOKMOBI = Mobi
