I just wanted to let people know that the airport express with airtunes

is REALLY COOL! I bought one some time ago and was using it mostly as a portable router while travelling (linking up to hotel ethernet connections in my room). I had tested out the "airtunes" capability, but never really used it much. Last weekend I brought out some speakers and set them up, and plugged it in at home. Now from any computer in my house I can wirelessly play any music through those speakers. So I just setup a computer in another room to run iTunes with a nice playlist running, and I have music all evening for a holiday party/dinner party/whatever.

Also, since the speakers are just getting input from the stereo jack via the airport express, I just quickly unplug that and plug in my ipod or a friend's if I have something i want to listen to there. It's really convenient, better than I had imagined.

So I just wanted to endorse this for anyone, it works using iTunes on a PC or a Mac and it's really a nice little device. Costs about $119 at most places.
