Even with a case I wouldn't put any kindles in my pocket. Not that I could fit it in there. I don't think I could fit even a half kindle in my back pockets. I think manly pockets are much larger than girly ones.
. I can barely fit my phone in it and its a 5.5 screen. But I could not do anything but stand stick straight with it. How do you bend, how to do sit, move.
I shudder at the thought of the stress on that screen.
