Thanks for that link. I probably just spent too much time reading through it. :-D
I read a few pages then jumped a few pages back from the end when I realized the conversation was moving significantly further then I should respond to.
After watching a few more youtube reviews with Clara and Calibre, I'm heavily leaning towards buying one and disabling wifi until I have reason to give up my data to Kobo (or wipe the OS for something in my control). I've never had regrets about financially supporting Calibre but I've never quite known how extensive and powerful it is until now. I've only used it locally for so long that it's been worth it. If anything, this experience/research has just made me appreciate Calibre even more!
