That Airport Express/AirTunes thing is just downright cool. I just set up an Airport access point for my mom over the weekend (she just bought an iBook and is getting broadband installed today, so we put the Airport in a closet in the middle of the house). Because of my main computer needs, I have always used PC's, and it's been over ten years since I spent any time in front of a Mac. I was very impressed with the interface. I think there are some more flexible and powerful media servers around, but the AirTunes approach is intriguing (especially if you already had an Airport base station).

I'd try the second zone and see what effect it has on the sound -- I doubt using it will have an impact on the life of the 950.
