I'm getting crashes on attempts to add stations. And this still needs a well-thought-out set of instructions. For instance, it ought to be explained somewhere that the category folders are the equivalents of the iTunes "Smart" playlists, i.e., they will only accept items that match their filter criterion, which appears to be their name. So you can't simply open iTunes and drag in a Public radio station to the Public folder, since most of those stations in iTunes are categorized as Talk, or Classical, or Various or whatever. You would need to change the category to get it to the folder you want. And you only get one choice (and no user-defined folders); you can't, so far as I can tell, classify a station like WNYC-FM, which is a talk station by day and Classical at night, so that it appears in both folders.
$30 seems a bit much to me for SW that is essentially still being brought up to snuff. At half that I might take take a flyer.
