Dh has a dock which streams Internet radio (last fm is what he uses). He does use radio apps to eg listen to radio 4/world service , but at home and for music he listens via Last.fm instead of any particular radio station. I got it from the Apple store, and was about £150 ish.
Natural light/awakening alarm clocks are ace too - we have one of those, but it pre-dates our iPods so isn't a dock as well, just a radio/alarm clock
