I have the Kindle Fire edition of The Message, and I just love it! I use it when I'm reading my Bible to help clarify or get a slightly different perspective on a passage of scripture. It's fairly easy to navigate, although not as intuitive as I would expect, as if you go through the whole table of contents to find the book for which you're looking, it takes forever. But if you go to the actual Contents, then you have a list and can select more easily where you want to go (this really is my only issue with it, but once I figured out the fastest way to get to where I want to go, it's been great).
Love Peterson's use of everyday language to bring the message to life for a new generation. Well loved passages feel brand new and allow for new insights and understanding. Numbered verses make it easier to study with others and the timelines and Story in Five Acts are a helpful addition.
