Good points, all of them. But for some folks, it might feel like "piling on," like being nickel and dimed to death. But for almost everyone, it's a matter of priorities. What you can afford versus what you cannot. For me, when I moved into my first house (after years of apartment living), I gave up cable TV. I have never had any newspaper or magazine subscriptions for very long. And right now, I am underemployed, after being let go from my last station three months ago. Once I achieve full employment again, I will strongly consider satellite radio. But for right now, it is a luxury that I cannot afford. I have kept my high-speed internet (couldn't stand dial up!), but it now costs slightly more than it would if I had kept it as part of my package deal with cable TV which I gave up. If I were to sign up for satellite radio, I would probably have to give up something else to offset the cost.
The way I see it, people now pay for reruns of what they could once see on free TV, so I suppose it's no different that people will now need to pay for what they used to be able to hear for free over terrestrial radio.
