Actually, I think that kind of "unnatural" love is not related to the Kindle. I've had my BeBOOK for a bit more than a week now, and I find it very hard to ever let go of it. Wife is getting a bit upset with me for that as well
But seriously, I think investing in an e-book reader is about the best thing i ever did! And I seriously hope i never fall out of love with the thing!
