It would seem to me in this burgeoning digital on the go age that any device that would combine more than one of these offerings would be explosively popular. If, say, the iPod were to incorporate a sat radio receiver into it, it seems like that would be a very good marriage for the device. Now some say that there would be a subscription conflict. That people would opt for the sat radio content (since listening to it is paid for by the subscription fee) over the bought music files from iTunes.
