Since I mostly listen at home, I'm getting a lot more enjoyment out of my new Internet radio than I did out of XM. I can listen to local stations from other places, as well as multiple versions of music from my favorite decades and genres. Considering how the local news-talk stations are spending most of their time lately on national politics, rather than local, it's becoming easier to see the advantage of radio that comes in over the 'net from other places.
Once mobile broadband becomes affordable, there's no way I'd choose satellite radio over Internet radio.
