Hi, I just bought an external hard drive for our airport extreme. Would it be a good idea to have our iphoto and itunes libraries on that hard drive, so that the various computers that we are using can access the libraries wirelessly? If you think it is a good idea, how would you go about moving the itunes library? I think it's easy enough for iphoto, but itunes seems a bit more complicated? If you don't think this is that efficient, do you have any other suggestions? Thanks so much!
