So, just to clarify...
1) Buy the book on Shortcovers and download to my Mac (via the web browser interface? Or the Sony Software?)
2) Open it in the Sony software to 'validate' it
3) Quit the Sony software, load it into Calibre and I am good to go on my Sony or on any device of my choosing
Do I have this right? The book is $11.99 so I want to be sure before I plunk down for it
