Assuming we all live "normal", crime-free lives I don't see a problem. Even by being on this internet forum you are being tracked somewhere, by someone. Apple have just announced that they will be monitoring iPhones for child-porn in the next iteration of their OS and that the technology can track other things such as financial transactions etc if they wanted, or were allowed to do it. And if that is what they have publicly announced, just think of the surveillance capability they are keeping secret.

You can either welcome the internet into your life or switch everything off and stay in the cave. (Even my TV and fridge are listening to me typing this!)
