Why do people buy the new Iphone every year?

I'm sorry, but I'm just wondering why the hell people waste $200 or $300 on the new Iphone when it has a LITTLE change to it. It's ridiculous and I just want to know… Why.

Ask someone who did

Because Apple know how to market their products.

You should read my last question i posted in this section just now about this.

Hardware is greatly improved. The fact you say so little changes tells me you know absolutely nothing about it.
