Good responses all, for which thanks ~~ except I can't see where Hobson's Choice, interesting a phrase as it is historically ~~ an antomomasiac eponym-metaphor based on the early C17 Cambridge University carrier's practice in his horse-hiring sideline of only offering any hirer the horse in the nearest stall to the entrance ~~ fits into the subject of the thread, WAV. And 'wireless' perhaps rather a somewhat obsolete synonym of 'radio' than a fossilised survival of a superseded technology: even when digital, radios are still wire-less in that sense, surely?
