Will enough folks prefer subscriptions over simply SCANNING for stations?
Perhaps someone in our forum uses XM or Sirius and can comment on how replaceable it can be (like the Betamax or Videodiscs of the 1980's) now that this new FREE digital radio service makes simply pressing one's "scan" button on one's increasingly better radio more appealing to folks who prefer NOT to pay $10 bucks a month for variety without as many commercials.
