Hi! I'm new myself.
Like your wife, for years, I disdained faux books. I am a dedicated bibliophile, and I adore paper!
But this is a really attractive gizmo. It feels nice in the hand. It's very like a book, without the dust and wormy issues. And yes, I have some books with wormholes. Ugh. And instead of having two to three dozen books in the trunk and passenger floor of my car and stuffed in my handbag, I can carry three dozen plus in one Reader. That was one of the reasons I wanted it. The compact nature. I have the King James Bible, several poetry classics, a Nano Hopkinson SF novel, a health bestseller, Shakespeare's sonnets and A Midsummer Night's Dream (decided to reread it after rereading the Neil Gaiman SANDMAN homage to it), and a Martin Luther commentary. And all that doesn't weigh much in my purse.
I had 33 items in there before, but I just purged today and reloaded it lighter.
Enjoy the REader. I'm learning to handle/use it myself currently. Maybe after your wife tries it out, she may find she wants some of her books in the contents.
