So Apple raised the price $100 since its introduction in 2007. That raise is LESS than inflation.
Look at the rise of Gas prices, food, water, housing, eletricity, since 2007.
16GB is not unusable. I had a 5S than a 6+ this year. I only use 10GB of storage. I own a 64GB model.
Stop talking for the entire WORLD saying 16GB is not enough.
Like I said this is like clothing. Do you grumble that Men's jeans cost more than kids jeans? Do you write letters to Levi's that its unfair that the kid's jeans cost $20 while the Men's jeans cost $30? Bottom line is if 16GB does not fit your life style get the 64GB.
And if the $100 upgrade is too much then maybe its time to switch to a non-premium brand.
Actually the original iPhone was $600 WITH A CONTRACT, until they later lowered it.
