New iPhone rumours abound. It seems pretty likely that bigger screens are coming in response to customer demand.
I prefer one that fits in my pocket, but women generally carry a handbag anyway so I assume that carrying size isn't as much of a factor as screen size for the girls?
Whatever happens we can be pretty sure that increased screen real estate is part of the new iPhone features.
It will of course come with iOS8 which has plenty of stuff to be excited about including catch-up with some Android features. But as for ease-of-use? Apple are still miles ahead and I speak not from prejudice, but from regularly being asked to do some configuration on a Samsung. It ain't as easy as on an iPhone!
