Here’s my take on the future of smaller iPhones.
And this is how we get to have a 4-inch iPhone, but not the one we were all looking for. The future 4-inch phone would be an iPhone 6c. Yes, you are right! Plastic case, many colors and iPhone 5s internals with an upgraded camera and Touch ID.
Are we going to be happy with that? Hell NO! This would not be a full-fledged new generation iPhone, but a dumbed down iPhone 5s in a slimmer, more colorful package.
