JohnDuncan:Or airport express, which is what I'm going to do - is a pain remote-controlling it, but will probably go down the iPod Touch route.......
I have to say, since getting the Remote software installed on my Touch, I do use this feature quite a lot now. Not to mention numerous other applications I use on it like Golf Tracker to keep a track of my golf score improvement, Live Trains, DVDDash, plus numerous games.
