Thinking about taking one of our AppleTV2s on vacation with us so we'll have access to our music (iCloud) and media (iTunes purchases & Netflix). Can anyone who's done this give feedback and any tips for quick setup? Will I just need to adjust the network connection or will I need to go all the way back through initial setup? It's been so long since I had to set up my two AppleTV2s that I can't remember what all is involved in setting them up for the first time on a wi-fi network. Also, my AppleTV2s work pretty well at my home and I don't want to jeopardize that ... I would hate to bring it home and run into trouble trying to get it running again on my home network.
