If you owned the company, you'd do the exact same thing. I'm tired of people complaining about things not being available on past iPhones. This is how business works, and yes Siri is capable of working on iPhone 4 but without the speedy chips it wouldn't be as efficient. AND YES, they also don't mind that people will buy the 4s simply for that. Stop complaining
we are customers, and customers are god. if the product has a problem, we have every right to speak up.
i grow tired of you justifying it because it benefits apple as a corporation by doing this. of course in their position they want to make more money, but that doesn't change the fact that this act is BAD for customers. and guess what? you ,me, and 99% of the people are customers, and we don't like getting f'ed in the butt.
