I don't want a 5.5" phone, nor could i use one. The 4.7" size is ideal for me, and i love using the iPhone camera, for actually printing photos and framing them, but i'm not willing to have someone force me to buy something i don't want or can't use.
Not everyone should be forced into something they don't need, that's the problem with these forums, most assume that the general public and others 'want' a bigger screen, 'want' this and 'want' that, when it's down to personal choice, and not what people think they want, just because that person 'wants' something in particular.
Everyone is different, has different tastes, needs, lifestyles and 'wants'. If we were all the same, it would be a real boring and ****** world.
