I think it's too little - too late for digital radio. Between Infinity, Clear Channel, and other biggies in radio broadcasting few people I know listen to most of the drivel on commercial AM & FM. Way too many commercials (especially during election season) and predictable playlists of the same stuff whether you're in Los Angeles, Tulsa, or Philadelphia.
If it wasn't for sports, religious and talk radio, many stations and broadcast groups would be off the air.
Most audio types I know listen to the local non-profit jazz station, Classical, or a few college stations. In addition, my McIntosh tuner does a nice job bringing in my favorite classical station. Why invest in something only marginally better?
