What you need is an Android Tablet. I feel that a Kindle is really only smart for heavy readers or people with limited access to electricity.

I have a Kindle and a Galaxy Tab. I use the Galaxy Tab daily, but when I go backpacking and don't have a charger I bring my Kindle. I would never bring my Galaxy Tab backpacking since it is heavy and there is not enough battery life. I don't really use my Kindle anywhere else since it is so much easier using my Galaxy Tab.
