I own 3-4 Airport Expresses, use them in my barn/barn apartment, to stream music from any open iTunes on the home network to powered speakers and an AV jack on a book shelf stereo plugged into an Airport Express. One I had a USB hub plugged into it with 2 printers plugged into the hub until I got my newest printer, which is wifi enabled. That Airport Express now has a ROKU plugged into it to join the home network to get some internet streaming content to my TV and a pair of speakers plugged in that I stream my iTunes to in the living room.
I've also got 3 Airport Expresses throughout the house and stream music from my computer to upstairs speakers, downstairs mancave speakers, and/or outdoor speakers by the lake. Stuff is simple and it works AUTOMATICALLY as stated earlier.
