For those of us who would like to read extensively in Logos on a tablet but do not want the limitations of a Kindle, what have users found to be the best reading experience? I am asking primarily about the screen here (not weight or dimensions); things like glare, brightness, direct sunlight experience. But also, as a current Android user I am curious to know from those who have used the app in IOS as well whether the layout, fonts, margins provide a more comfortable feel in one or the other OS.
