Just wondering how exactly Airport Express works. I would like to play my itunes library from speakers around the house, and control everything from my iPhone. I see AE should do exactly what I want. Problem is, now im reading I need a PC with wireless capability for this. I have a wifi network setup, but the PC that runs itunes is a desktop with no wireless connection. Will this be an issue? I was hoping to simply plug in the AE to the outlet and then to speakers and thats it. If this is not possible, can I just connect a LAN cable from my router to the AE and still get Airtunes out of it?
