Has anyone gone out and purchased a Digital Radio receiever ? If so, is it all its advertised to be ?? Can you see the added benefits of it ?? I have not met anyone yet who has gone out and purchased one. In my opinion, I think the basic services of radio is good enough - ie. you tune in and you listen. I know in the future it will call get transfered over to digital - but at the moment, I cannot see its benefits. . . . . opinions ????
