Most of my radio consumption is now over the Net ... mostly using streaming mp3 stations.
The BBC is an exception as it is RealAudio based and doesn't integrate into iTunes. I've been using Steam to get schedules and to invoke hte Real Player.
Recommended! You can even get Radio Cymru and Radio Gaidheal for texture.
I can't imagine missing BBC, CBC or NPR news - but then again I'm something of a radio junkie.
