Airport Express is ideal for those of us with our iTunes server located remotely from our primary home entertainment center (a.k.a. "the stereo" for you old timers.) My iTunes server is upstairs on the G4/Dual 500 in the home office, accessible from any system on my home's WLAN. Airport Express means that I don't have to dedicate a Wi-Fi enabled Mac to be plugged into the stereo. I'll be able to sit with my TiPBG4 anywhere in the house and select the content to be played over the stereo. That's pretty darn cool. And I get Wi-Fi range extension as well, so I should be able to take my TiPBG4 down another level to my garage (where I've got a second set of speakers off of the stereo) and select songs from there as well. My order is placed :-) Regards, Jim
