Very interesting; thank you for your responses.
I am a Mac user, but honestly, I'm still not familiar with anything technical about the Mac.
I looked at Calibre information, watched the video, it looks pretty easy.
However, is there some technical ickyness I have to go through to install on Mac? If so, is there a step-by-stem guide? My computer guy joined the Army, he's in boot camp, so I would be LOST without a guide to installation on Mac.
Again, thanks for your thoughts and advice. Much appreciated.
