FM DOES mean HD. HD is the standard...the only widely implemented format in America. If another format reaches this level of success, I'll eat my words. But with the stations that most Americans listen to (major market outlets owned by groups like Clear Channel and CBS) already in HD, and nearly all of the country now served by multiple HD signals...even rural areas like mine, yes...FM IS HD. The transition on the listeners side won't be instant. It won't even seem fast. It took 20 years (70s till the 90s) before personal computers reached "critical mass" and were anything but geek toys. HDTV is nearly a decade old, and most people I know don't have one yet. But they ALL say they'll get one when they buy a new tv. That's what'll happen with HD, too. The most popular types of radios (portables/walkmans) aren't even available yet. But thanks to companies like Bose, Cambridge Soundworks, and Tivoli, quality table radios, enormously popular in decades past, have made a comeback, and HD is growing like crazy in this sector. The Sangean component tuner is also great, and will be better when they bring out an upgraded version later this year. They are considering a version that will incorporate Wi-Fi radio as well as HD. That'll be a "must-have" at my house.
