OK I know Tivo and DVR's are for TV, but if we can send people to the moon, and come up with satellite TV and satellite radio, and a digital video recorder with all its bells and whistles, isn't it possible to do the same for radio?
As someone who really loves my satellite TV with Tivo, and my ability to watch something again and again, and pause it for trips to the kitchen or the bathroom, I can't tell you how often I find myself wishing I could do the same thing in my car. It annoys the hell out of me that I can't rewind my car radio to listen again to something I just heard.
I realize it would require a way of packaging all the radio channels into a computerized format, the way DirecTV and Dish Network package the TV channels.
Why can't XM and Sirius do the same thing with their radio channels and sell radios with built-in digital audio recorders?
