Yes, we get a phone out of it, but that phone is so we can buy apps, pay providers for service (fine, except we pay out the nose for things that aren't even really necessary like text message plans on smart phones that don't need them), they sell us the device, or the apps, and then track us, monitor us, and sell that information so that they can better target and sell us more stuff.
We're not just the consumer, our habits are a product.
But that's my knee jerk doom and gloom response, something I keep in the back of my mind when I work on more rational reactions.
