Quite frankly, why would anyone? There are places where automation and real time data feeds make sense, like an ICU for example. I have to honestly ask myself, what would this bring me? Happiness? Peace of Mind? Not really. I'm already connected enough. I don't want my appliances, car, whatever... jacked in. I see no real benefit, but a lot of risk.
When I upgraded my phone the decision not to get a smart phone was easy. What is the payoff? I give easier access to corporations and/or government easier ways to keeps tabs on me. What would the benefit be? More access to email? Woohoo! That is exactly what I'm striving for. I've long accepted the fact that I'm really not that important and perpetual access is not something that I really need or want. I have a gps in my car. It gets me in the ballpark without being a transmitter. I'm not scanning UPCs to see what a better deal I can find at the spot. If it's that important, I will do the research and make a decision. Plus, I also like brick and mortar stores. I knowingly pay extra in the hopes that I can help keep them around. In particular, I fear the demise of bookstores. I've found some real gems going into a local book store and perusing.
That is not to say that the internet doesn't have its place either. This last weekend I was able to replace the stepper motors in the instrument cluster of my truck thanks to youtube and finding the parts on the internet.
