Based on this story at The Digital Reader (
http://the-digital-reader.com/2014/0.../#.U5714rGwMg8) - I'm thinking a color e-reader maybe (?) - this book can only be read on a Fire tablet, NOT on a Paperwhite .... hmmmm
Or is the storyline being used as an extended metaphor to launch a really different 'purple' phone - just to be different from all the other 'white' phones that all look alike?
