I thought it was sheer stupidity to just make the iphone 5 longer not wider but now in hindsight it was ingenious,do I thing it will work again?No! Now do I want a bigger screen? Yes but its gonna have to be a sweet spot if I wanted to carry around a ipad mini all day thats what I would do I would say somewhere between 4.3 and 4.7 would be a good starting point but what do I know.
