After downloading and printing out the drawings, I immediately knew the 4.7 would be better. In addition, the last few days I've been paying closer attention to my one-handed texting and phone operating habits. It was astonishing to learn how much functionality I would be giving up going all the way up to 5.5. 4.7 is a comfortable jump while still having one handed functionality. Everyone keeps thinking about how it will fit into pockets. What about one handed operation?? Does it matter to anyone?
