I couldn't help but notice that you said that it will keep the kindle "safe and warm". Maybe it's just a misconception from my part but doesn't anything electronic prefer the cold?
From what little I understand about electronics, I do believe you are right. I think most electronics do prefer the cold. That is my mother's wording on the site. I'll ask her if she would like to change the "warm" to "snug" or "cozy".
