I read several of the prior reviews and almost didn't get the NIV. So glad I did anyway, because I quickly realized that most of the NIV Kindle reviews are from those using the Kindle Reader. I use Kindle on my IPhone and it works great - maybe because it of the touch-screen technology. I'm currently on a daily Bible Reading schedule so I needed to get to the places I left off quickly. The Kindle on IPhone works differently than on the actual Kindle reader obviously. I can dog-ear the pages by tapping the right top corner of the IPhone. I can highlight passages just like in my paper Bible (I use yellow, but there may be other colors available). I can even write notes right at the passages. I can quickly get to the table of contents. I know I haven't used all the features that are unique to the Kindle on IPhone but I'm using the feature that I need on a daily basis. All and all I'm extremely pleased.
